Abstract
Mitochondria may serve as biologic clocks. This paper provides plausible explanations, based on mitochondrial aging, of some aging phenomenon: a) the inverse relationship between basal metabolic rate and life span; b) the antioxidants studies thus far which increase the average life span of mice, depress body weight and fail to lengthen maximum life span; c) the association of degenerative diseases with the terminal part of the life span; d) the exponential nature of the mortality curve, and e) the beneficial effect of caloric restriction on degenerative diseases and life span. A short discussion is also presented of the effect of exercise on life span and aging of muscle mitochondria.
