Officially an asshole

So you know how for the last couple of weeks there have been pictures of Alexander Litvinenko, the former Russian KGB member, all over the internet. I was pretty intrigued by the story and really hated what happened to the guy for obvious reasons.

The entire time, however, I kept wondering how come the polonium he was poisoned with made him lose all of his hair but his eyebrows persevered. I didn't mention it to anyone as I didn't want others to think what I already know: I'm a total asshole.

Today I came across an article that actually explained away my precise concern:

Radiation causes hair loss because it tends to damage fast-growing cells like those of the germinal layer of the hair follicle. But there's likely to be more hair follicles engaged in active growth at any given time on your head than in your eyebrow region. (That's why people have to cut their hair more often than they trim their eyebrows.) This fact might explain why people who are undergoing chemotherapy—or who get poisoned with polonium-210—seem to lose hair from their scalp first.

Pretty damn interesting, no? And, yes, perhaps I AM an asshole, but clearly I am not the only one.
