Done some of that. More to do.
Had a couple of phys ed teachers in high school who were not into the usual UK triad of (soccer/rugby/cricket). I had already started ultra-distance running myself, and they supported and encouraged me, including inviting me to go a race (the Manx Mountain Marathon) with them. Having people around who not only told me there was nothing crazy about this sort of thing but who actively celebrated and loved it totally changed my life. I've been an endurance athlete ever since, and about 6 years ago managed to track one of them down (35 years later) to thank them for what they had done. It was a great phone call.
Right now, I'm writing a letter to a semi-famous solar inventor (Steve Baer) who really influenced me when I was a teenager growing up in London. I implemented one of his patents as my high school physics final project (an osmotic heat pipe), and then visited him at his zome home outside of Albuquerque, NM. I reached out to him about 20 years ago to see if he still remembered me, and he said "Of course! You're that Brit kid who built the heat pipe that Hughes stole from me". As fate or luck would have it, I now live about 50 miles north of him in a tiny village in New Mexico, and would like to see him again and thank him once more for the many different ways he influenced my life. Letter should go out tomorrow.
