If you any singular person and gave them a better diet with more exercise they would be healthier, fitter, probably have more energy, Likely live longer, etc. Having an exception where one guy I know who was in great shape died young, or my great grandmother smoked til 97, doesn’t change that the overwhelming vast majority of people would benefit from being more physically active and eating a better diet. The exception doesn’t make the rule.
