The New York Times's Well Blog published an interesting article on how even five minutes of running can extend a person's life by 3 years. The article suggests that exercise intensity is part of the key to improving longevity and that the type of workout does not matter. If running bothers your knees and you just don't like it, consider buying a stationary bike to get the same benefits.
