Scientists say the higher your I.Q. the more you dream.

The largest cell in the human body is the female egg and the smallest is the male sperm.

You use 200 muscles to take one step.

The average woman is 5 inches shorter than the average man.

Your big toes have two bones each while the rest have three.

A pair of human feet contain 250,000 sweat glands.

A full bladder is roughly the size of a soft ball.

Your body gives off enough heat in 30 minutes to bring half a gallon of water to a boil.

When you are looking at someone you love, your pupils dilate, they do the same when you are looking at someone you hate.

Loud noises make the pupils of the eyes dilate.

Seeing something that makes you happy makes your pupils dilate, and seeing something you hate makes them contract. This is a good way of telling whether or not people really like you. If the sight of you makes them happy, their pupils will get bigger, and vice versa.

Synesthesia is a rare condition where people's senses get mixed up. People may feel tastes, see sounds, or hear colors.

Lag (yeah, that's me) is sort of a synesthete. In my experience, I have always associated every number and letter with a color. I can associate people's voices and personalities with color, too, and if people have very unusual or striking voices, I can taste them.

Only 1% of the world's water is drinkable.

There are no muscles in the fingers, just tendons attached to the muscles in your arms. To prove it, prop your elbow up on a table and hold your hand straight in the air. Wiggle your fingers and watch the muscles on the underside of your arm move. Creepy, huh?

An estimated 1,000 women die in childbirth every day. (Another one to add to the list of reasons for not having children!)
