Do you know how much skin is shed at any one time? It's 600,000 particles!

Do you know that you have fewer bones than a baby?
Editor's note: Try counting the two hand bones shown above. How many bone does a child's hand (left) and an adult's hand (right) have? Do you manage to count 23 and 13 bones respectively?
As babies, humans have about 350 bones. However, some bones fuse together during growth and thus ends up with only 206 as adults.
Do you know that the acid produced by the stomach to help digest the food you eat has a pH value between pH 0.8 and pH 1.0?

Do you know that the length of the small intestines is 4 times as long as the person’s height? This means that if a person is 154 cm, the small intestines will be 616 cm!
