Rate of living theories of aging emerged from the observation that metabolism is generally slower in larger, longer-lived species. There are enough exceptions to disprove any specific hypothesis regarding what exactly might limit life span in species with a fast metabolism, however, and for this and other reasons rate of living theories fell to the wayside, somewhere along the way towards the development of a modern understanding of cellular biochemistry. Nonetheless, we are left with the observed that, yes, larger species tend to live longer, and yes, species with slower metabolisms also tend to live longer. Exceptions aside, that does suggest that something is there to be learned.
Here, researchers propose that the count of respiratory cycles over the course of a lifetime is the underlyi…
