Even our closest relatives, the great apes, move smoothly from their juvenile to adult life phases – so why do humans spend an agonising decade skulking around in hoodies?

Today, most researchers reject Freud's belief that dreams are expressions of our unconscious desires – but if that's the case, what are they for?

Many of us have superstitions – odd, reassuring habits that make no rational sense – but there may be an underlying reason for such behaviour

The ends ae white because the nail bed is attached with tissue and has blood flowing through them. So when your nails grow, they arnt attached to any blood flow, they just come out white

Yah, I just googled it. :p

You'll whole fingernails are actually the same color (a slightly transparent white). But the tips are not pressed against your skin, so they don't get the tannish tint that you actually just see because of the transparancy of your fingernails. Hope I cleared things up!
Sounds like a good answer.

Now homosexuality on the other hand, that makes no sense :p
