I heard this somewhere and can't remember where ... but I thought it was interesting because of my Irish heritage and that my brother is red headed. I had fire engine red hair when I was young ... hence my nickname is Rusty. (most people people call me "Rus").
My best friend's daughter is one of the most beautiful red headed girls I've ever seen ... shame that those in the future won't be able to see such beauty.
Fact: Scientists predict that due to the decrease in family size, abortion rates, divorce before children, women getting married later in life (and more importantly after child bearing years) and the fact that red hair is recessive - that there will be almost zero red headed children in 100 years. ~ from www.redhedd.com
