Ever wonder why Jack LaLanne keeps on chugging along into his 90s, looking and sounding as vital and healthy as he ever did on his TV program 40 years ago? A review of studies reports exercise slows down the effects of aging and help a person maintain his or her cognitive abilities as they get older, more evidence that physical activity -- not a drug -- can do wonders for your mental and physical health.

For instance, seniors over age 65 who exercise for only 30 minutes three times a week have a better chance of avoiding Alzheimer's disease, even if they're predisposed to it than those who don't.

Scientists also uncovered connections between fitness training and improved cognitive powers (more efficient brain functioning and retained brain volume) in older folks. And, various animal studies have demonstrated the durable ability of their brains to function in different areas than expected and to protect or offset the effect of various diseases, all thanks to exercise.

That's why, one of the best investments you can ever make is to commit to a regular exercise program you can do for the remainder of your life. Just remember, the trick about exercise is to treat it like a drug that must be prescribed precisely to do any good. If you're worried about a time commitment, you'll want to review recent articles written by personal trainer Ryan Lee that demonstrate how you can get the exercise you need in as little as 12 minutes.
