Healthy aging is a hot topic for baby boomers everywhere.  Whether you're concerned about weight gain, sex drive or chronic diseases, the key to healthy aging is a healthy lifestyle.  Eating a variety of healthy foods, practicing portion control and including physical activity in your daily routine can go a long way toward promoting healthy aging.  Better yet, it's never too late to make healthier lifestyle choices.  If an interest in healthy aging leads you to consider anti-aging therapies - such as restrictive diets, supplements or expensive treatments claiming to postpone or even reverse the aging process - be cautious.  There's no quick fix for healthy aging.  Know what you're buying, and know how to spot suspicious schemes.  Often, anti-aging therapies don't live up to the claims.
