Washington, Mar 10: A new study, led by Lobke Vaanholt (University of Groningen, The Netherlands), has cast significant doubt on the theory that a higher metabolism means a shorter lifespan.
In the study, the researchers found that mice with increased metabolism live just as long as those with slower metabolic rates.
The theory that fast-living animals die young, known as the rate-of-living theory, was first proposed in the 1920s.
The faster you expend energy, the faster you age, and the sooner you die. It remained a prominent theory of aging until recently, when comparisons across broad animal groups cast doubt on it.
