People with fast metabolisms have shorter lifespans

People with fast metabolisms have shorter lifespans

The study's results may not come as a big surprise to animal researchers, who have long noted a strong link between lifespan and metabolic rate in non-human animals. Small creatures with quick metabolisms and rapid heart rates, such as mice, have much shorter lifespans than animals with slow metabolisms and heart rates, like elephants. Humans fit into that spectrum as a species too, but until now there has been little evidence linking metabolic variance within a population of humans with lifespan.
