Yeah, just heard it on the radio. I don't follow any of the celebrity chefs so I really don't know much about him. Perhaps it had nothing to do with success, but more about health. Robin Williams was diagnosed after his suicide with Lewy Body Dementia, but for months had many symptoms that were never properly diagnosed (he was misdiagnosed with Parkinsons). One of the problems with the misdiagnosis is that while Parkinsons medications will relieve some of the symptoms, they make others much worse. Unfortunately there is no cure, but perhaps a few more years were possible in his case.
