I am not a sports watcher..I'd rather play than watch. But by reviewing my research and online communities (thanks Liz) I recall Tom Brady's serious infection in his knee in 2008. Do you think it's a coincidence he re-injured his knee last week? I think not. Bugs eat tissue with their enzymes. That's why many people have joint diseases in this country.
