That is an excellent list of lifestyle factors, but suggesting that genetics impacts 10% or less of biological outcome is pretty bold.

Put another way: everything is nature, nurture and “random”. It’s rare to find an outcome where one of those three completely dominates the causal equation.

That's why I said most people (within two standard deviations from the mean roughly), there will be people for which their genetic component will make up a larger part of why they seem to suffer from low energy.

That doesn’t follow. Genetics very much influence the factors cited within the 90%.

If I am understanding your argument correctly, certainly agree that e.g. "some people are more genetically inclined to drink". But I think It’s valuable to draw some boundaries between what we can and cannot control, even with genetically varying difficulty.

To state my original point in a potentially clearer way: I suspect there is significant genetic variation in energy, controlling for lifestyle habits. Evidence: 1) Personal observation over years of interest in this topic 2) the fact that there is extensive variation in most quantitative life outcomes, controlling for lifestyle habits
