Hi Steve. Very interesting and I believe in positive thoughts and fighting through whatever. I have had back pain for years, at one stage I was going in to have epidurals so they could manipulate me on a table. I manage it now and have even be tempted to the occasional round of golf. I know I shouldn't, but you only live once. I have a high pain threshold and I am sure that helps.Sometimes I don't even know how bad things are but I put it down to mind over matter and have become head strong. I know my injury hasn't improved, but I have in how I control it.
