Michael French suffered from a rare form of dementia. It made him do unwise things like throwing away tax documents, getting a ticket for trying to pass an ambulance and buying stock in companies that were obviously in trouble. He seemed withdrawn and no longer spoke to his wife over dinner. He also lost his job at the consulting firm. This happened in 2006. His wife found he had changed suddenly from the smart, good-natured, hardworking man and was considering divorce when his ailment came into the picture.
