In many papers one can read that telomeres may play an important role in longevity. According to Calado et al.1 the telomeres of mice are much longer than the telomeres of humans. However, mice have an average life expectancy of about 2 years and humans about 80 years.
Does the metabolic rate therefore determine how fast the telomeres shorten? Can one say that the higher the metabolic rate, the faster the telomere shorten?
