Get off the couch to fight cancer

If you don't want cancer, you've got to get off the couch. Now, I don't promise you won't get cancer if you change your couch-potato ways -- I got cancer and never was a couch girl myself -- but this one simple step will at least offer you some protection against the disease we all want to keep at bay.

Don't worry, you don't have to work up much of a sweat in your fight against cancer. Simply moving will do the trick. Sure, a hard-core run works but so does a round of golf. Or a walk with your pooch. Or a game of kickball in the back yard with your kids. Any type of physical activity will do -- as long as it's not done while reclining on the couch. Jumping on your couch might work, though.

No one knows for sure why exercise is a cancer butt-kicker. Maybe it's the inflammation and stress-fighting powers physical activity delivers. It doesn't matter why it works, really. It just works. So get walking, dancing, hiking, raking, mowing, and more. Just move.
