My dear Mom was 86 Alzheimers took her. She always thought that doing crossword puzzles would prevent her from getting Alzheimers.
It didn't!!!!
Like me she had emphysema. And like me she lost her driving privelege; which put her into a deep depression. Her husband died and no one to take care of her, until my sister and BIL took her in; she slipped and fell on a hard Mexican tile and broke her back.
