No all older or elderly people have shut themselves away though. My 86 year old dad didn't. Carried on seeing his friends who were similarly out and about, they still had their weekly poker nights. he is on his own so was coming to stay with us once a month.
Dh 94 year old grandmother was still getting the bus into town every day for a walk about as were her friends.
In laws in their 70s we're doing as much as was still allowed, still seeing family and as soon as they could were booking meals out and weekends away.
I think the idea that all older people have been sat at home scared is over the top. None of the older people I know were remotely bothered.
(Obviously not taking about people in care homes, and yes, I do realise that many people were and still are terrified but it's just not been my experience with people I know).
