I think Paul Stamets is going to be one of those genius we will only learn to appreciate after their death. Those pioneers that are so far ahead they get dismissed. His applications of fungi go from medicine to pest control, and probably also touch material engineering.

I sometimes feel I should change field completele and study mycology due to the things I've read and seen from him !

Combining those two with Vitamin B3 (Niacin) supposedly does wonders for circulation or something along those lines. I can only attest that the niacin flush makes me want to rub and massage my body everywhere because it feels so nice and warm.

(Note: long term daily extreme doses of Niacin may contribute to liver problems)

The book "How to Change your Mind" by Michael Pollan has a good profile of him (and several other people and groups mentioned in this thread).

Paul Stamets is incredible. Don't miss the many youtube videos and podcasts with him. Every single one will blow your mind.
