This guy is so cool...been living in the rainforest off the land in the Hoh Forest of the American Northwest for 25 years...he's not just a 'wilderness' guy, he is also a fitness buff, and a Barefoot Runner ;-)
They have a show on National Geographic channel about him.
Neat guy, great sense of humor, and a barefoot/minimalist runner...(wears moccasins in winter after a frostbite episode years ago).
He had a bad case of planter fasciitis years ago, took off his shoes and went running/walking in the forest to fix it, and never came back lol
