Hi olderman!
By the time the average person gets to their 50's +, their bodies just are not as capable of absorbing the nutrients from their foods because their intestinal linings and colon are so built-up with residues and bacteria that block intake. If you are serious about anti-aging or slowing down (and possibly reverting the aging process), here is what I recommend:
1. Obviously, make sure you maintain a healthy nutritious diet, but diet alone will not help because the body can't absorb nutrients as stated above.
2. Try a body detox/flush regiment to allow the body to break down the residues and plaques in the intestinal lining and eliminate them so your linings will be refreshed. You can read my "How to Detoxify Your Body"
3. Take Xtend-Life Total Balance. This is simply the most effective multi-nutrient and will actually work to repair your cells and also rebuild your body's natural testosterone and HGH levels. Not to mention what it does for your libido and energy levels. I take them myself...I am 33 years old and I still get carded for R-rated movies :-) and constantly get compliments of how young I still look. When is the last time you felt 25 years old, olderman?
4. Exercise! Even if you do this in moderation. My favorite is brisk walking for its many outstanding benefits and low-impact. Weight lifting is also good as weight-bearing exercises are what REALLY strengthen bones and joints. If you would like a simple weight program, please let me know or I should have it posted on my blog soon.
Live well, Be Healthy - olderman!
