But I'm a long-time devotee of regular exercise, and this latest study on lab mice underlines that exercise really does seem to be the magic bullet.
While it would be hard to test the same theories using weight-training (although I'm enjoying the image of mice doing tiny little bench presses and squats, I can tell you from my own life that weights are definitely part of the magic-bullet equation as well.
And never mind that every now and then you end up with a bit of an injury from too much enthusiastic gym time (like at this very moment, in my case). Weight-training helps restore the muscle we start losing in our 30s as part of the aging process. For every pound of muscle on your body, you're burning at least 10 times the calories just maintaining it as a pound of fat burns in the course of a day. What's not to like?
