some things about the human body

when you are born you have over 300 bones in your body but when you reach adulthood you only have 209

babies are born without kneecaps

baby chimps are smarter then human babies

your liver can grow back even if three quaters of it are removed

the length between your wrist and your elbow is the same length as your foot (if not your a freak)

your eyes are the same size when you are born and when you die because they stay the same size your whole life

your ears and nose dont stop growing though

if you live in the city your earwax is darker and thicker then if you live in the country

some people have a third set of teeth

your stomach acid is strong enough to dissolve steel razor blades

if you could scrunch together all the bacteria living on the outside of your body they would take up the same amount of space as one pea

all the bacteria inside your body would fill six teaspoons

if you dont sleep for two weeks you will die

if you unravled all the little tubes in your kidneys and laid them out end to end they would strech for 80 kilometres (50 miles)

however they are scrunched up into space thats only 10 centimetres (4inches) long
