My 85 year old husband refuses to shave or even take a sponge bath.It is almost two months since his last one.I feel he feels he doesn't have control over many things but by not bathing or shaving he can still control that.He almost looks like a homeless person. Same underwear for two or more weeks unless he messes himself and then I give him a clean pair of undewear. But he still won't bathe. I don't know what to do. Does anybody have a solution to my problem?
