When Robin Williams' wife told the world yesterday that her husband was in the early stages of Parkinson's Disease, Michael J Fox Tweeted that he was stunned that he didn't know about the diagnosis. Apparently since Robin Williams had frequently supported Michael J Fox's charity over the years he thought Robin would come to him or talk to him about the diagnosis. Fox has previously said that the diagnosis made him depressed and that he spent a year drinking alone when he found out he had the disease and that it took him a long time to come to terms with it. I wonder if that diagnosis just became too much for Williams to take. This is a guy who lived for physical comedy. Ad libbing and improv and thinking on his feet and trying to be as wild as he could during his comedy. Maybe the thought of not being able to do what he considered himself the best at doing would limit him somehow and combined with his depression and relapse was just too much for him to handle.
