Looks like Picard's work supports the "rate of living theory".
For example, in his
Cellular allostatic load is linked to increased energy expenditure and accelerated biological aging
hypermetabolism, defined as "increased energy expenditure", it is concluded that "a robust and specific temporal association between hypermetabolism and premature cell death, aligning with prospective observations in the human literature where hypermetabolism increases mortality risk. Finally, our experimental modulation of OxPhos and total J_ATP suggest that total energy expenditure, rather than flux through mitochondrial OxPhos, may have a particularly influential effect on cellular aging".
Hmm... but the references that they use could be mined further for some gems.
