Telomeres are the ends of your DNA that shorten as you age. This is the reason a dog lives 10-15 years while a person lives 70-100 years. The dog's telomeres shorten quicker, so they age faster. In effect, by not getting this amount of exercise, your telomeres are about 10 years shorter than the guy down the street who does.
I see middle aged and elderly patients all the time who are in too much pain to exercise. They have chronic knee, hip, shoulder, problems that prevent them from being active. The problem is that this impacts not just their overall health, but likely how many years they have left. These patients need to find non-invasive ways to get out of pain. The Regenexx procedure in one way to fix that joint pain without being out of commission for 3 months. Whatever you decide to do to help your injured or arthritic joints, one thing is clear, getting active will help more than just your heart, it will also extend your warranty!
