Does the amount of energy you expend over time technically make you “older” because your atoms are moving more than someone who moves less?

Someone at work brought this up and my head almost exploded because it sounds like total BS. They said if a sedentary mother gave birth to a baby who grew up to become an extreme athlete (ultra marathon runner/someone who just never stopped moving their whole life), technically the baby is “atomically” older because more energy has passed through them. Is this just malarkey?

Well the way your colleague put it is totally irrelevant, however there is some merit to the overall idea that energy throughput accelrates aging. Nothing to do with single atoms or whatever though.

There is evidence (https://www.cell.com/cell-metabolism/pdf/S1550-4131(11)00264-6.pdf) that the more energy that you use, the faster you age. That is to say ***food*** energy from your diet. Why? Nothing to do with ‘atomically older’ or such nonsense. The more food you eat, the faster your metabolism, and the faster the products of metabolism create free radicals/ Reactive Oxygen Species, which are molecules which catalyze all kinds of negative reactions with your body chemistry, including damaging your DNA. These effects compound over time, making you age faster than if you were free from free radicals.
