My mother-in-law is 83 with severe rheumatoid arthritis. She is still of pretty good sound mind and living by herself in her home. She is spending more and more time in bed. Eating a very poor diet, and her mobility is very poor. She probably should not be driving. She does not see a need for help. One of her sons would like to put a care plan into action, but the other two siblings have a wait until there is a crisis attitude. Suggestions? (I'm the wife of the one who is concerned, but we live 350 miles away).
