Query: Younger Is as Younger Does

Of all the anti-aging books I've seen, this is one of most laid back and entertaining. It's written by two guys. Harry, the doctor, covers the science aspects of aging, while the other guy, Chris, talks about applying the info.The book is centered around "Harry's Rules." These are seven rules for the reader to follow. They include such things as "Quit eating crap" or "Exercise six days a week for the rest of your life." While they might seem to be basic pieces of information, they are sound advice and have some science behind them.All-in-all, I found this to be a very informative and amusing book and I'd recommend it to anyone who is looking for a book on aging. The realistic key here is not to go into things thinking you're going to STOP the aging process, rather think of SLOWING DOWN the aging process.
