The older generation have, to a large extent been fully vaccinated and therefore it is more likely that either they will not get it or it will not be as serious. The virus is not going away, and it will continue to mutate. At some point we are going to accept that people will get ill and some may well die, just like happens with flu.If we keep locking down every time a new variant turns up we could well find that the "cure" causes more problems than it solves.
