I agree with the gist of this article: we need more adversity. Working with heat and cold is the most efficient way to get there, although HIIT and even short bursts of exercise help. I am a big fan of simply standing up often, thus using our frenemy--GRAVITY--to create much-need adversity. When it comes to diet, I don't think we humans have a consensus and the research is lacking. The Mediterranean diet works but it isn't as vegetable-centric as advertised and varies widely in practice.
