Unbelievable Facts about the Human Body 

 

The Human Brain

 

1.      The human brain is made up of nerve impulses that can travel as fast as 170 miles in an hour. Have you wondered how fast you can react with painful stimuli such as burns, sharp objects and inflamed skin? This is because nerve impulses help the brain; kidneys and heart function normally, sending appropriate signals at the speed of a high powered luxury sports car.

 

2.      The human brain has the ability to function like a 20-watt light bulb. It remains a mystery how our brain can generate great notion swiftly. Even when we sleep, our brain still generates the same amount of energy just like a miniature light bulb.

 

3.      The human brain can store large information as much as 50 times of a Wikipedia.

Or any other popular encyclopedia for that matter.  It has been mysterious for thousands of years that even scientist have yet to confirm how much the brain can store information. It is, however, a fact that the brain’s maximum capacity ranges from 3 to 1,000 tetrabytes. Amazingly, even the National Archives of Britain which contains thousands years of historical books can only take up to 70 terabytes, creating your brain’s storage capacity totally extraordinary.

 

4.      The human brain needs at least 20% of the total oxygen in your system. The human brain weigh just like a one kilo of fruits. However, it requires more oxygen than any other body organs. The human brain is a very sensitive organ, it can automatically sense if there is not enough oxygen in the body. Therefore, you should breathe deeply keeping your brain healthy and other body cells full of oxygen.

 

5.      The human brain is 10 times more active during nighttime. It’s a weird fact to know that during daytime, you can do things with full of energy, like going to school to study, going to the office to work or even perform complicated tasks and mathematical calculations right away compared to lying in bed and doing nothing during nighttime. But not knowing that it’s the opposite of what the reality is basically. When you turn off, the human brain turns on. Cool! Experts don’t yet know why this is. However, you should be thankful to your brain for working so hard just to give you pleasant dreams.

 

6.      Experts say the more dreams you can recall, the higher your IQ is. While this may be true sometimes, don’t take it too serious if you cannot recall what your dreams are last night. Many individuals cannot recall their dreams and only for about 2-3 seconds in average hardly long enough to register.

 

7.      Nerve cells continue to live throughout human life. For hundreds of years, doctors and experts consider that human brain and nerve cells couldn’t multiply and regenerate. Not like the other tissues in the body, nerve cells persist on multiplying throughout your life. This makes the brain more interesting to study especially those diseases that are associated with it.

 

8.      Different neurons travel information at varying speed. Each neuron is different. Transmission of information differs from each other depending on the kind of neurons. They can travel as slow as 0.5 meters per second or as quick as 120 meter per second.

 

9.      The human brain itself cannot sense painful stimuli. Even if the brain is known as the pain center sometimes, where it can sense an immediate cut on your finger, the brain itself lack pain receptors and cannot feel the pain. However, it doesn’t mean that your head can’t be injured. You can still experience throbbing headache as the brain is enclosed by nerve tissues and blood vessels containing pain reception.

 

10. The human brain is made up of 80% water. It is important to keep yourself hydrated always because doing so can prevent brain injury. Human brain contains soft, pinkish and jelly-like organs and not those hard, gray mass you’ve seen on TV. This is because it contains loads of blood and water, cushioning the brain against sudden injury.

 

 Healthy Hair and Nails

11. The fastest growing hair is no other than the facial hair. It is necessary for men to keep himself clean by shaving his beard daily. However, if he ignores this practice, then he should be ready to see his beard growing up to 30 feet long, or even longer than a killer whale.

 

12. The average daily hair fall is about 60-100 strands. Did you know that you can shred hairs quickly? Yes, it’s true. However, hair loss will depend on your age, the season, nutrition, and genetics not unless you’re already bald.

 

13. Men’s hair diameter is twice of the women’s hair. While it might sound a bit weird, it should be a surprise that men’s hair should be coarser than that of women. Hair diameter actually depends on age, sex, race, season and diet. It’s important to consume enough protein making your hair healthy.

 

14. A single human hair can hold up to 3. 5 ounces of liquid. This is equivalent to two full-size chocolate bars. This fact including thousands of hairs seen on the human head makes Rapunzel tale believable.

 

15. The middle finger is considered the fastest growing nails. Mostly, the middle finger on your dominant hand grows the fastest. It is true that the longer your fingers are, the faster the nails will grow, while the shorter your fingers are, the slower the nails will grow.

 

16. There are millions of human hairs in our body than an ape. Human hairs are not created the same as other animals. We actually have millions of hair existing in our body it’s just too difficult to see them as some are too light or fine to be seen.

 

17. True enough that blondes have more hair. It’s fun to know that blondes have definitely more hair than other race.  Hair color signifies how thick the hair on your head is. On average, every individual has 100,000 hair follicles and each has the ability to multiply up to 20 individual hairs during his entire life. On the other hand, blondes average 146,000 hair follicles, while individuals with black hair have 110,000 hair follicles. However, brown hair tends to have an average of 100,000 follicles while the least dense hair goes with the redheads, having only 86,000 hair follicles.

 

18. Nails located on your finger grow 4 times faster than your toes. Have you noticed that you most probably trim more often your fingernails than your toenails? This is because nails that are more exposed and often used grow the fastest. Each month, average nail growth for both fingernails and toenails is about one tenth of an inch.

 

19. On average, human hair live for about 3 to 7 years. Imagine your hair living up to 7 years that are much longer than other animals. This is possible as long as you give importance to your hair, taking care of it most of the time and protecting it against harmful chemicals. Here, you can appreciate the different styles and haircuts for many years before they die on their own.

 

20. Before someone describes you bald, you must lose at least 50% of hair scalp. It’s normal to fall out 100 hairs a day, but not to the pain that millions of your hair have already been gone. Others can only notice your baldness, if more than half of the hairs are already gone.

 

21. Human hair is nearly impossible to destroy. Human hairs decays at a very slow rate, aside from it flammable property. It’s pretty amazing to know that our hair can endure any type of climate even if its winter or summer time, they would still survive. Human hairs are also resistant to very corrosive and acidic chemicals.

 

Internal Organs

22. The small intestine is the largest internal organs in the body. Small intestine is often called the smallest between the two intestines. However, if you will carefully look at your intestine, it is basically four times as long as an average adult. In order to the keep intestine fit inside the abdomen, it is no wonder why they are looped back and forth that way.

 

23. The human heart can generate adequate pressure squirting 30 feet blood. The heart is one of the major organs in the body. It can generate pressure enough for it to distribute blood throughout the body. Keeping them well-supplied of oxygen, as their primary source of food, without it, other organs cannot survive.

 

24. Human stomach is very acidic that it can possibly dissolve anything else. The acid that is responsible for this is commonly called the Hydrochloric Acid (HCL). They normally exist in your stomach, which functions in food digestion and protecting the stomach against harmful chemicals. You don’t need to ingest a non-food thing just to prove that your stomach can actually liquefy them. Many studies have been conducted and proved that HCL can actually dissolve metals.

 

25. The human body contains thousands of blood vessels that it can reach for about 60,000 miles. If you try to visualize the distance around the earth, it in an average of about 25,000 miles while your blood vessel could travel twice around the earth if place end to end.

 

26. Your stomach lining shed off every three to four days. Because of acids present in the stomach, the mucus-like cells lining the stomach walls diminished, not unless it is continuously replaced. This can then result to ulcer. Imagine how painful it can be when stomach acids acts directly on your stomach lining.

 

27. The tennis court is equivalent to the surface area of a human lung. In order to supply adequate oxygen throughout the body, the lungs containing tiny grapelike alveoli and hundreds of branching bronchi must receive enough blood oxygenation to work efficiently. Lungs are made up of microscopic capillaries where oxygenation takes place. Thus, lungs need to occupy larger surface area making blood oxygenation much possible.

 

28. Women’s heart pumps much faster than men’s. This is because women on average tend to be smaller than men, which has lesser blood mass to pump. Women’s heart act differently than men especially when having a heart attack. That’s why men and women should be individualized in terms of the amount of medication they need, making sure that it will work perfectly for them.

 

29. Liver is beneficial to every human being; in fact it has more than 500 unique functions. Liver is vital to life. Several functions include biotransformation, filtration of harmful chemicals including alcohol and nicotine, breaking down of medication, production of bile, plasma protein synthesis and detoxification. It is one of the hardest, biggest and busiest working organs in the body.

 

30. The diameter of the aorta, the largest artery, is virtually a garden hose. On average, an adult heart is nearly the size of two fists, making the size of the aorta totally extraordinary. It is ideal for the aorta to be that large, as it serves as the main provider of oxygenation throughout the body.

 

31. In order to make room for the heart, the left lung is normally created smaller than the right lung. Since we were children, we used to believe that both lungs are equally structured. However, it is due to the heart, which is primarily located slightly on the left side of the ribcage, crowding the poor left lung.

 

32. You can still survive even you remove a large part of your internal organs. It is possible that one can live even if other body organs have been removed due to health risk such as the stomach, the spleen, 80 percent of the intestine, 75 percent of the lover, one lung, one kidney, ovaries and other organs located in the groin and pelvic area. You may feel too conscious about yourself, but at least you can still live with curtailed body organs.

 

33. Adrenal glands vary in shape and sizes throughout life. The adrenal glands are normally located above the kidneys. They secrete hormones such as adrenaline and cortisol. These hormones are released during stressful situation keeping the body in equilibrium. When you were only seven months as a fetus, your adrenal gland is the size as the kidneys. During birth, the glands begin to reduce in size and will continue throughout life. When one gets old, it is difficult to locate the glands as they are too small to be palpated.

 

Bodily Functions

 

34. Regular sneezing can exceed 100 mph. There’s a good explanation why you can’t maintain your eyes open when you sneeze - as sneezing can go for a speed of 100 mph. This is, certainly a good reason when you sneeze to cover your mouth.

37. A person having full bladder looks almost the size of a soft ball. It is a reflex for every person to go to the bathroom every time they feel an urge to void. The amount of fluid that triggers urination is around 250-300 ml. On the other hand, the average bladder can hold for about 400-800 ml.

 

38. Fecal matter is made up of 75% water. Not only is the urine that we see commonly made up of water, but also the fecal waste product of our body. Be sure to drink enough water as deprivation of fluid can result to constipation, a painful condition, where one passed hard dry stool.

 

39. Human feet can generate more than a pint of sweat daily as it contains 500,000 sweat glands. Men typically have much more dynamic sweat gland than woman does. Due to the body active sweat gland, it’s no doubt that your shoes have a stench on it.

 

40. Combining all saliva produced entirely can create two big swimming pools. The body produces enough saliva daily, which is useful in the digestive processes, keeping the mouth lubricated preventing fissure.

 

41. On average, each person expels flatulence at about 14 times daily. Even if you don’t agree with the fact that the body normally produces gas as a byproduct of metabolism, the reality is all people should expel these gases otherwise, it can lead to stomachache, which you wouldn’t like to happen.

 

42. Earwax is important for proper ear functioning. Many people find earwax as a dirty thing. However, it’s a very useful substance that cleanse, lubricates the ear while enhancing ear’s defense system. It also safeguards against fungus, bacteria, insects, and dirt.

 

 

 Sex and Reproduction

  43. Sexual intercourse occurs around 120 million times on earth every day. Human can proliferate million times and with most people having sex daily can affect the current health population. Nowadays, it’s no wonder how fast the birth rates are in different countries worldwide.

 

44. The female egg is the largest cell in the human body while the male sperm is the smallest. The female ovum is chiefly the largest cell visible in the naked eye with the size of a pea, having a diameter of about a millimeter. While other cells like muscle cells and skin cells can’t be easily seen. On the other hand, the sperm cell is a minute cell that can only be seen with the use of a microscope.

 

45. During the first trimester of pregnancy, the three most common things that pregnant women dream are worms, potted plants and frog. It is common to observe mood swings, food cravings and many other unexpected changes occurring during pregnancy and this is due to the hormones being released. This however, can mostly influence the kind of dreams women have as well as their vividness. These are the three most common thing women dream, but there have been reports that others dream of giving birth, having violent and sexually charged dreams and even water.

 

46. Teeth begin to grow while you are still a fetus. Although some children born have teeth with them already, these will ultimately be visible in your child’s gums that are formed long before the child is born. At around 8-12 weeks, the fetus begins to form the teeth buds that will evolve into baby teeth.

 

47. All babies are born with blue eyes. The color of a person eyes will depend on his genetic make-up. For instance, if your parents have blue eyes, then there is 100% probability, that you are born with blue eyes as well. During birth, most babies appear to have blue eyes. This is due to melanin pigmentation. Melanin often needs time shortly after birth to be fully stored or to be darkened by ultraviolet light exposure, which reveals the baby’s real eye color.

 

48. Don’t underestimate babies as they can be as strong as an ox or probably more than that. While babies definitely couldn’t pull a wagon at its current size, it may be possible if the child were the size of an ox. Watch out for babies kicks as they have very powerful and strong legs even if they are such tiny creatures. 

 

49. Studies show that one out of 2,000 newborns has their tooth with them. Many mothers would disagree with this fact. Often, the tooth is an ordinary baby tooth that has erupted and often it is an extra tooth that will fall out long before the new sets in.

 

50. Fingerprints can be possible with fetus three months of age. Fingerprints, unique human traits, do exist with fetus and has developed before they are born. These fingerprints formed at 6-13 weeks will remain permanent throughout the person’s and will only disappear after he dies.

 

51. Every individual have spent half an hour as a single cell. All living creatures has to begin somewhere else, and believe me each of them whether the smallest or largest species have been a single cell organism for a short period of time after the egg and sperm cells united. They then begin dividing rapidly and forming an embryo.

 

52. Erection occurs more often in men. Most of them experience erection every hour and every one hour and a half during sleep. A person’s mind and body are more active when they are sleeping. Erection occurs during sleep as a result of combined testosterone production and blood circulation. They are considered normal physiologic processes occurring in the human body. 

 

 SENSES

 53. Hearing decreases shortly after eating excessively. Try to eat foods in moderate amount if you want to keep your hearing healthy. Otherwise, if you plan to go to concerts and discos after a big meal, then you may be compromising yourself.

 

54. One third of human race has a grade of 20/20 vision. Most people nowadays use eye glasses and contact lens making vision much clearer. However, person with perfect vision decreases as they grow old.

 

55. Taste can only take place after food has been dissolve by saliva. In order to taste the food, saliva must first dissolve the chemicals from that particular substance. If you think it’s impossible to believe, why don’t you try tasting something while drying off your tongue.

 

56. Compared with men, women are born better smellers throughout life. Women can better distinguish smell of vanilla, citrus, coffee and cinnamon. Although it has been known that women are in general better smellers, still 2% of the population have no sense of smell.

 

57. Your nose has a powerful ability to recall 50,000 varying scents. While lore of vampires smell is million times more sensitive than humans do. However, that doesn’t signify that the human sense of smell is of no use. Humans can recall different scents and may powerfully store to memories.

 

58. Pupil dilation can occur even in whisper. That’s why in the operating room, where surgeons, watchmakers and other surgical members such as nurses, anesthesiologist uphold the rule that it is a must to keep noise to a minimum. Even whisper sounds can be a hindrance in a successful operation making efficient tasks harder to achieve.

 

59. Each person has their own unique smell, with exception to identical twins. Most newborn babies can distinguish the smell of their mother, and significant others. However, genetics chiefly affect how each person smell. Another factor includes diet, personal hygiene and environment that create a unique scent for each person.

 

 AGING AND DEATH

60. The average weight of ashes after cremation is about 9 pounds. Water plays a big part in our body. It occupies almost 80% of the human body, giving much weight. Water and other body tissues are destroyed once cremation occurs, leaving at least 2 kilos of weight behind.

 

61. Nails and hairs cease to grow soon after death occurs. Some nails may appear longer shortly after death, however, when dehydration draw closer, hairs and nails gradually shrink.

 

62. As we age, our sense of taste decreases especially upon reaching the age of 60. Old people including your grandparents tend to lose the ability to taste accurately. In order to appreciate a dish, they add more flavoring using salt and sugar when cooking. So watch out when grandma cooks for your meals!

 

63. Human eyes are generally permanent since birth unlike ears and nose that keep on growing. Growth and development continue until a person dies.  Except for your baby eyes that are already permanent, which you will be carrying around for the rest of your lives, the ears and nose are as well.

 

64. Snoring is possible by age 60 for both sexes. Studies show that 60 percent of men and 40 percent of women will have great chances of snoring. It’s a fact that hearing someone having a snore is pretty annoying especially when this person sleeps beside you. There are different levels of snore, 60 decibels on average, the normal level of speech and 80 decibel as intense snores.

 

65. As human grow, brain and total body length changes significantly. For instance, a baby’s head is 25 percent of its total length, but by age 25, total lengths will only be 12.5 percent. As we can see, huge sized baby heads won’t change size as much as the rest of our body. The head will not grow that much unlike your legs and torso that lengthen.

 

DISEASE AND INJURY

66. The risk of heart attack is greatest during Monday. This fact remains a mystery. A study conducted in Scotland found that 20% more people suffer and later on die from heart attacks during Mondays than any other day of the week. This is due to too many activities over the weekend accompanied by stress of returning to work.

 

67. A person can live without food for months, but not without sleep. Average person can survive without any food for a month or two, only water, but not without sleeping. Sleeping is very important in our life. This is where we can recharge and be able to function normally. Going without food for a long period of time is possible, depending on the total body fat and other factors. So far, the longest recorded time a person has ever gone without sleep is 11 days. However, the results were not that favorable. The subject experiences hallucination, stumble over words and cannot recall what his name is and what he is currently doing.

 

68. Even simple sunburn can damage the blood vessels severely. How severe? One study conducted in the US showing that it normally takes four to fifteen months for blood vessels to regenerate returning to normal condition. Always take precaution when being exposed to sun. Wear sunscreen with at least SPF 30.

69. Stress can generate or complicate over 90% of the diseases. Many health conditions such as high blood pressure, diabetes, heart diseases and depression are caused by stress.

70. Even it has been decapitated, a human head can remarkably remain conscious for about 15 to 20 seconds. It has been proven that without the presence of blood in the head, it can keep a person alive and conscious for few seconds. That is incredibly true!

 

MUSCLE AND BONES

71. There are 17 muscles that work when we smile and 43 muscles when we frown. Smiling is a much healthier option to choose, not unless you want your face have a bit of exercise. Frowning all the time is not ideal for most of us. It will only tire your face, doing nothing to improve your temper.

 

72.  Adults have a total of 206 bones while newborn babies have 300 bones in total. This is the result of immature bone structure; some of them have not yet fused and mostly are flexible. No wonder babies can pass easily on their mother’s pelvis without being harmed. However, as they grow, bones are fused and become harder and stronger.

 

73.  We are much taller in the morning than in the evening. The reason for this is the cartilage between the bones are being compressed as we stand, sit and doing other activities. At the end of the day, we become 1 cm shorter than at the beginning.

 

74. The tongue is considered the strongest muscle in the human body. Even the tongue seemed so tiny and weak; it is in wonder the strongest muscle existing in your body. Using your tongue when you eat, talk or even sing is a good form of exercise, keeping it strong and healthy.

 

75. The jawbone is the hardest bone in the human body. If someone told you to take it on the chin, you might be well-advised to take their suggestion as the jawbone is considered strong and cannot be broken easily.

 

76.  When you walk, you utilize 200 of your muscles. A single step can use somewhere in the neighborhood of 200 muscles. Considering most of us take 10,000 steps a day. That’s lots of work for those muscles!

 

77.  The only part of the human body that can’t regenerate itself is the tooth. Unfortunately, it sad to hear that a broken teeth cannot repair itself because the outer layer is made up of enamel considered none living tissue. Any problem you have encountered with your teeth would require the dentist’s assistance.

 

78. Losing muscle takes much longer than building it. This can be a good motivation to some people. Being patient enough can build new muscle tissue and get your muscle in shape. So, continue doing regular exercise. It’s not only good for your body, but can keep you in shape as well.

 

79. Bone is much stronger than some steel out there. Bones can of course break if force to. But they are much less dense than steel. Bones have a tensile strength of about 20,000 psi while steel has around 70,000. Bone is much lighter than steel, however, pound for pound bone is much stronger substance.

 

80. The feet contain more bones than any other part of your body. It has been a fact that feet account for about 25 percent of all the human body’s bone. Out of 206 adult bones, the feet specifically contain 52 all in all.

 

MICROSCOPIC LEVEL

 81. Your skin normally contains about 32 million of bacteria. This is known as Germaphobes, but you don’t need to worry them much as majority of them are totally harmless and some are even beneficial to us. Keeping us protected against the harmful environment.

 

82. Every 27 days, humans typically shed and renew outer skin cells. Skin is the largest body organ so far, which functions in protecting delicate internal organs from dryness and shed off completely every month to maintain its strength and durability. Have you wondered why your bed or desks have dust? This is due to your dead skin cells that have flaked off.

 

83. Millions of cells die every minute in the human body. Specifically, about three hundred million cells expire from time to time. However, it is replaced with a total number 10-50 trillion cells so it would be okay to lose a few hundred million without compromising your system.

 

84.  On average, each person shed about 600,000 particles an hour. It’s a normal mechanism for your skin to shed off and regenerate on its own. As you can see, having sunburn can be harmful to your skin as well as blood vessels, however, thanks to your skin’s ability to renew automatically, your skin will be good as new in no time.

 

85. Our body produces about 300 billion of new cells daily. To keep your organs and body tissue healthy and functional, it should be able to constantly repair itself, regenerate new cells and shed off dead skin cells.

 

86.  Just like fingerprints, every tongue print is unique. No tongue prints are alike. If you are planning on doing something unlawful, don’t think you can’t be traced after leaving a tongue print behind. Each tongue is created unique and it can easily identify you as the perpetrator. Be cautious as DNA is the most accurate way to identify you as the culprit other than the previously mentioned identity print.

 

87. Your body contains enough supply of iron that can even create a 3-inch nail. Human blood has a slightly metallic taste. This is because of the presence of iron in the blood. If taking out of all iron present in the body is possible, then it would be enough to produce a tiny nail. However, watch out for severe anemia, a fatal complication associated with lack of iron and red blood cells in the body.

 

88. Type O, the universal blood type, is the most common globally. Type O blood is very useful and blood banks find it very valuable as it can be given to that person having Type A, Type B or Type AB blood. However, it’s nice to know that the rarest blood type is A-H or otherwise known as Bombay blood due to place where it was discovered. This blood type can be found in less than a hundred people as of the present.

 

89. Due to the presence of many capillaries below the skin it has created the lips to a pinkish- reddish appearance. These capillaries are highly oxygenated giving the lips red in color. If a person is anemic, there’s no wonder why his lips also look pale because of lack of blood and oxygen on that particular part. Have you also wondered why lips turned blue during winter? Cold temperature causes the constriction of the capillaries, reducing blood flow and oxygenation, resulting to a darker lip color.

 

MISCELLANEOUS

90. If you sleep in a cold room, the greater the chances of having a nightmare. This fact remains a mystery for some experts. But if you don’t want to experience bad dreams every time you sleep, it is much safer to at least keep yourself in a warm room.

 

91. Tears and mucus contain an enzyme called Lysozyme, responsible for cell wall breakdown of harmful bacteria. Illnesses can be prevented with the help of that mucus lining your nose and throat, as well as, tears being produced by lacrimal glands. These substances are helpful against bacteria, infection causing you to become sick.

 

92. Your body has the ability to bring half a gallon of water to a boil in just half an hour. Human body normally generates energy potential. Our body can burn many calories than we think keeping us warm and can reach up to 98.6 degrees, same temperature use to cook pizza and boil enough water.

 

93. When you feel scared, your ears produce more earwax. Some chemicals and hormones released when you fell scared have unintentional effects on your body producing earwax. Studies showed that fear causes both ears to secrete more earwax, though there has been no explanation regarding this phenomenon.

 

94. Tickling yourself is never possible. Even when you tickle yourself in all your bodyparts, you will not be able to respond to any stimuli. This occurs because your brain predicts from the information it already has, especially how your fingers will move. The brain doesn’t react in the same way as it would if your friend was doing the tickling.

 

95. The length of your whole body is congruent with the width of your arms span if stretched out. Your arm span is a good estimator of your height, while not perfectly aligned to the last millimeter.

 

96. Human beings are the only animals that produce emotional tears. Human beings are considered crybabies in the animal world. They are the only animals who cry for some certain reasons such as they have lost their loved ones, not feeling well or have a broken heart.

 

97. People who are right-handed live much longer, nine years on average than left-handed people do. Genetics have nothing to do with this. This is largely because of the fact that most of the tools and equipment we use every day are specifically designed for those individuals that are right-handed. Making the lefties prone to accidents and deaths each year because of trying to use a machine with the use of non-dominant hands.

 

98. Men have faster metabolism, burning more calories than women does. Women have slower metabolism than men, by a difference of about 50-110 calories daily. This is because of women’s reproductive role, requiring a much higher body fat proportion than men. Thus, women find it more difficult to get rid of excess fat, eventhough they exercise that much, still body fat goes with their body structure.

 

99. The only animals with unique fingerprints in the animal kingdom are the koalas and primates. Apes, humans and koalas are uniquely created with tiny fingerprints. Studies have suggested that primates that have been cloned still have unique fingerprints with them.

 

100.      Did you know that the area between your nose and upper lips has a name? Yes it does. In fact, as you see that there is an indentation in the middle. Scientist called this the philtrum. Experts have yet to discover what functions does this indentation has. However, ancient Greek considered philtrum one of the most sensitive parts in terms of sexual stimulation in the human body.
