He's 85 and completely on the ball mentally, but his mobility has decreased dramatically in the past year. He went from playing golf and driving to using a walker and hardly being able to move.
He shouldn't be living alone. He has a girlfriend (my mom died 3 years ago) and she's really lovely, but she isn't there all the time. She's also 75 herself, so she's not able to do a lot of heavy lifting with him, which he needs, because he can't get out of a chair without assistance and sometimes falls down, (even with the walker) and needs to be picked up.
He recently hired a home health aide, but she only works five days a week. This is his choice--he doesn't want to pay someone to be there seven days a week, even though he is very well off financially AND has long term care insurance to cover some of the cost.
I'm afraid that he'll fall when someone isn't around and really injure himself. He insists he's fine. Any suggestions?
