We all (okay, most of us) have hair - but how much do you know about the stuff that grows on our head? AskMen has a neat article on the 5 things you didn't know about ... the human hair:

4- Redheads may be aliens
There’s a conspiracy theory that redheads are alien-human hybrids. Think about it: Why did several kings and queens of Europe have red hair even though, percentage-wise, redheads are fairly rare? Why do so many Southies have red hair and speak a different language than other Boston locals?

It sounds crazy, but carrottops do have biological differences other than appearance. Redheaded women bleed longer, which is why doctors make special preparations for them in childbirth. They also have the smallest hair count on their heads, about 90,000 as opposed to 140,000 on people with blond and brown hair. That’s why Kick a Ginger Day began, just to keep these possible aliens on their toes.
