Exercise is still good, but it doesn't do magic if you live unhealthy the rest of the time.
(That being said, I wonder if the extreme types of workout many people promote is actually good, or if it does more damage than good in the long run. I guess some people believe that one extreme can out-weight another extreme.)
Quote: " "Jim" Fixx (April 23, 1932 – July 20, 1984) was the author of the 1977 best-selling book, The Complete Book of Running. He is credited with helping start America's fitness revolution, popularizing the sport of running and demonstrating the health benefits of regular jogging. Fixx died in 1984 at the age of 52."
