Exercise as potent medicine?

An interesting article in the New York Times: Exercise as Potent Medicine, by Gretchen Reynolds (Dec 11, 2013).    It describes how a large-scale study showed that when exercise is evaluated in the same way as drugs, in many cases it provides a similar level of benefit!   One of the study’s authors said: “We are not suggesting that anyone stop taking their medications,” he said. “But maybe people could think long and hard about their lifestyles and talk to their doctors” about whether exercise could and should be incorporated into their care.
