Hehe. Most people I know were born blonde, but their hair-colour has darkened over the years. Common phenomena AFAIK. It'll be harder to get rid of everyone with blue eyes..
I was blond for the 1st several years of my life and then my hair became "chestnut" (my mother's term).
My grandmother had yellow eyes and both my parents have blue eyes.
I have hazel, sometimes green eyes, changing depending on forces I know nothing about.
I guess when I die that will become extinct too.
:-D
