My father needs a wheelchair in the morning and evening after he puts on pajamas. With a brace, he can walk. My girlfriend has MS; without thresholds, life is easier, some days nothing works without a walker, in bad phases the wheelchair is necessary, A buddy had a stroke, is doing quite well, manages well on his own, he uses a walker in the bathroom so he can stand more firmly. Should they go to a nursing home? Would you put your husband in a nursing home if you are completely fit but he is no longer? It is the decision of the OP, but anyone who is considering moving to the ground floor in old age should, in my opinion, think about accessibility. Even if you don’t need it, it makes life easier not to have thresholds. Does it hurt anyone if the doors are 10 cm wider? Does it bother anyone if the layout allows limited wheelchair or walker use? I am not talking about disability-compliant construction, as some have to do here.
