You mentioned how you enjoy walking barefoot and touching trees and it reminded me of something I heard recently about how we need to be physically/electrically grounded, like in physical contact with the earth for our bodies to be functioning more optimally. As opposed to getting loads of sticker burrs in my feet, where the person went with it is they ran a metal strip over their bed to sleep on and a wire from it to a rod in the ground outside. Don't think my wife would approve of such practices, though, lol!
