далеко не правда. за старение ответственны гены + образ жизни , а не скорость обмена вешеств.

Could mice hold the secret to longer life? Scientists from the University
of Aberdeen, the Aberdeen-based Rowett Research Institute and the Medical
Research Council (MRC) in Cambridge have made a major breakthrough in
understanding how metabolism affects lifespan.
In a seven-year study of mice they found that those with the highest
metabolic rate lived the longest, raising the prospect that the effect
could be mimicked in humans.
Scientists have long thought that a high metabolic rate was linked to a
shortened life-span. The present discovery turns this century old belief
on its head and changes dramatically our understanding of the regulation
of life-span.
Metabolism is the means by which nutrients are broken down to smaller
building blocks and chemical energy, which are used to make new body
materials and to do work.
The researchers discovered that the most metabolically active 25% of the
mice studied, far from having shorter life-spans, in fact lived 36%
longer than the least active. If the same effects are mimicked in humans
then the finding would imply that a higher metabolic rate could add an
extra 27 years to the average human lifespan.
