Earlier this month, a reader posed a fantastic question that prompted today’s post. It was long, so I’ll give the choice bits rather than quote the entire thing: Where do I start? I’d be interested in seeing your opinion on the relative impact of various primal lifestyle changes… Eating “clean” would be a 10, etc… but what about subtler things like sprinting, IF, quality sleep, sunlight, and play… So I guess I’m asking you to write on a 30,000ft level, how all these things interplay and what their relative contributions are to overall wellness. Where does one start indeed?
