There’s been a lot in the news lately about the question of longevity. This past week an article discussed the role of exercise in “biological aging,” the relative age of a person based on biomarkers (determined by telomere length in this study), rather than simple chronology.
To add to this discussion, I want to offer up a medically accepted dimension of biological aging that hasn’t gotten as much press lately. Lean muscle mass in happy tandem with organ reserve are two defining characteristics of both good health and longevity.
Have you ever heard someone say that a person died of “old age” or “natural causes”? Essentially, the person died as a result of the logical end of the aging process, the diminishment of organ reserve and corresponding muscle mass that supported his/her physical functioning.
