1) A higher IQ is correlated with more dreams. Our conclusion? Nerds are dreamier.
2)By the time you go to bed at night you are about 1 cm shorter than when you woke up that morning. This is because the cartilage between your bones is compressed throughout the day.
3)There are more than 300,000,000 capillaries in your lungs and if they were stretched out tip to tip they would reach over 1,500 miles.
4)You are hot. So hot, in fact, that in just 30 minutes your body can produce enough heat to boil a half gallon of water.
5)Except for identical twins, every person on earth has a unique smell.
6)Your brain is demanding, as it uses about 20% of your entire body’s oxygen and caloric intake.
7)Your bones are strong. Very strong. In fact, one matchbox sized chunk of bone can support over 9 tons of weight, or four times that of concrete.
8) Your skin is the largest organ in your body and in a male adult, if it were to be stretched out, it would cover roughly 20 sq ft.
9) The digestive acid in your stomach is strong enough to dissolve zinc, which begs the question, how on earth does it stay there? Simple, it’s because your stomach cells are renewed more quickly than the acid can destroy them.
10)To grow all the way from the base to the tip, your finger and toenails can take up to half-a-year.
