When I retired, I joined a Fla State program as an Ombudsman. I was there " for " the residents ( volunteer position ).
I can tell you from a been there, done that, position. Age means nothing to the sex drive.
Early on I discovered something I didn't expect. If two folks, not related " fall in love ", they let em move into a room together. Even in a NH, life goes on for a while. Not a bad deal, I guess.
