And there are questions about whether CABG really reduces mortality or not.
As for Zamboni's procedure, I was psyched about it until I read Rose's debunking, and then some posts in a forum for MS patients by someone who had the surgery and is still having problems with MS. I'm not going to say for sure that it's BS, but I'm skeptical.
