I'd go so far as to say that my self-experimentation has resulted in the unusual sensation of aging in reverse: as I learn more about my own body and how to make it function better I am continuously becoming healthier and more fit than I ever have been before. [...] I discover more and more ways of improving my own health which result in even better focus and even more productive work. I don't know how sustainable this trend is, but I'm going to find out.

Sounds like a material for an interesting discussion (maybe even main, if well documented) post. Please write one!

As a general remark, not just for you -- I have noticed that many people underestimate how cool is what they do professionally. Probably because they are exposed to it every day, and speak every day with people fluent in that topic, they develop a bias "people already know this, it's nothing new, nothing to be excited about". Yet for a person unfamiliar with that topic, many seemingly trivial details are exciting (and unfortunately, the non-trivial parts are often incomprehensible).
