A recent article in the AARP newsletter covers aging and chronological vs. biological age. I won't go into detail, but it has to do with cell reproduction. The very first point is that if one walks briskly it tends to subtract 20 years from biological age. It also mentions that long-term studies show that those same people tend to live to 85 (men) or 86 (women).
Just found this interesting. I haven't finished the article yet. I may post additional findings.
