I'm very interested in all this stuff - basically anything that isn't CW is interesting to me. Years of working in a hospital has convinced me that we are, collectively, barking up the wrong tree with most of CW medicine. It's great for certain things, but wellness is not one of them.
I was talking with some co-workers about lightning strikes a while ago, and we were wondering why people are told not to shelter under trees, and why the charge jumps from the tree to a person. I guessed that it is because human beings are much better conductors than trees are, but I really have no idea. And when I worked at a large and very famous hospital in Boston I used to see a lot of electrocution victims - often cable workers. Although it was quite horrible, it was also fascinating. Okay, I'm going to a morbid place here. Switching gears - I am convinced there is something special about contact with the earth and bodies of water. It's not just imagination. When I was a kid I spent hours sitting or lying or running on the earth, and as an adult it is something I stopped doing, as do most adults. In southern California I used to walk barefoot on the beach year round but that is not possible in most places. Okay, I have gone on long enough. Oh, one more thing - the Earthing book is mostly just a lot of 'testimonials' from people who supposedly experienced huge benefits from sleeping grounded. Really no science. Just a lot of "Jim Smith from Podunk, Ohio cured his a-fib after sleeping grounded for two weeks. The doctors were astounded." Save your money.
