Rogers and I have this in common; my hair turned almost completely snow white @ age 40 in about a week. I had just seen Mackris naked.

Not sure what happened to Rogers.

Here's the CNN version of the article, less sciency than the Nature piece.

I turned white headed just after 40. It was the first time I saw my provident fund and bank account after the divorce was final.

Wow. The Clintons burrowed deep under the skin of some.

And yet they wonder why they won't go away. Odd.

At 64, my hair (on my body and scalp) is almost still completely dark brown. Only my beard has lost its color. I guess I've led a pretty stress free life.

More importantly, what causes people to ridicule others skin color?

Orange looks good on Ommpa Loompas and Sesame Streets Ernie, not on supposedly adult men. As for your question, former President Obama probably wonders where, oh most of the hatred for him came from too.

Way too much ketchup on his hamberders and extra well done steaks.

Are you justifying skin color ridicule by mimicking the party you hate?

I wonder what inner force turns hair green?
