Not sure if you meant to say that, but I do believe you should do what you like and can in this short period on earth. Whatever that is and if it doesn’t hurt others, do it please, it doesn’t matter anyway.
However, almost all people I know that are over the top healthy (measuring everything, doing some sort of ‘du-jour’ diet (all meat, no meat, all protein, no protein, extreme fasting, no fasting; etc; ‘the best way to live’ changes more often than JavaScript frameworks), a lot of sports) are addicts to it or do it because they believe they will get a lot older than others (weird to me as many spend a of time doing stuff they don’t like; why would you want to lengthen your life in that case, but ok).
