Query: T.C. Fry has written a very eye-opening book.

If you think you know the cause of disease, then think again. T.C. Fry's "The Great AIDS Hoax," is one of the most eye-opening works I have ever read. It's not just about AIDS, but the cause of all disease, which will make you think twice the next time you think you can catch a cold or the flu. Even sexually-transmitted diseases don't escape Fry's logic, which is right up there with the greatest of scientific minds.
