My dad is 82 and has pretty much resigned himself to being housebound, and refuses to go to the hospital because he's very weak and frail (BMI of 16.9), and because he can't stand hospitals. He has an appointment for an echocardiogram tomorrow as the doctors suspect he might have a blocked valve that's causing a lot of his weakness. He postponed this last time because he didn't feel up to going to the hospital, and I suspect he is going to want to cancel again. On the one hand I want to respect his wishes to not go to the hospital, but on the other hand if this test is the key to getting him better and giving him a good few more years than I really want him to go.
