It would, if all people over the age of 65 lived alone. We live wit my in-laws, as do lots of our friends who didn’t have help from the bank of mum and dad. Most of our parents are over the age of 60, lots of them are over 65, but we are not. My MIL retired last year in January, but my FIL works in NHS, she is 65, he is 60. Does he shield with her and then NHS loses another worker? Do we shield with them? We have one friend where there are two children (one of them with his partner) live with their parents and grandmother on a big house, and everyone but the grandmother (she is in her 80s) work for NHS, and not as admin. It would be impossible to implement, because of so many people having to live with their parents and with lots of older people having to work because their pension is too low.
