I can see both sides to that.Surely it would be better if it was over 70's who have underlying issues who are isolated from possible infection ? No way y folk over that age should be left in a situation with family able to visit the for that length of time. It won't hold if they try to impose it....they will know this as well.
My Dad is 76, is ok wise and obv haven’t seen him in a while but dunno if i would gamble on his by visiting him anytime in the next few months.
Garden visits maybe.
