There was a gentleman at my club who would come daily to swim there. He said he had "Parkinsons". He had been a university violin professor. He was very intelligent and made good investments in the stock market, I paid attention to his tips. For years I would watch him arrive at the pool with the assistance of his wife. He would travel from the hot tub in a halting spastic like headlong run. It was frightening to watch, I was always waiting for the day he would stumble, trip and break something--he never did. He always stopped and jumped into the pool. He would do the same headlong run back to the locker room headfirst looking like he was out of control about to fall--he never did.
I remember once giving him a copy of Sarno when I was in a more proseletyzing mood. He took it and gave it back and said to the effect it was very interesting like most people who don't buy into TMS do.
One day he told me he'd just come from our local "one of the best teaching hospital's on the planet" and said they told him he didn't have Parkinsons. I asked him what the docs on the hill told him he had? He said they didn't know.
If you do a "search" here and at the other TMS site, you'll find more info on the topic.
