No, it is a joke I am playing on someone...

Guys and gals,
For the past couple of weeks I have been reading a really good book, which I highly recommend. The book, "King of Comedy" (The Life and Art of Jerry Lewis) by Sean Levy is one of the most well-written I have ever read. Goes into his background, breakup with Dean Martin, and the basis of why he often acts so wacky! It was published in 1995, and I just happened upon it as it was listed in another book by the same author I read. When sick with a cold or recovering from LIS (or whatever), I like to lie down and read. Just a suggestion!

Ancient asian steppe peoples like the Mongols, Huns, Turks, etc didn't do agriculture and mostly herded animals, and their diet was mostly milk, cheese and meat... my question is, how the hell did they all not suffer from AF's?

Better question is if they did have af how the hell did they deal with it?
