I would guess most people socialize less as the get older. Having kids and constantly drowning in work and household obligations will kill your social life real quick.

I definitely became less domesticated during the pandemic and I’m still not where I was beforehand, socially. I was even in my late twenties when the pandemic hit, so I should be less susceptible than teenagers/younger children were. It was worth it not to kill a bunch of people by spreading disease, but it wasn’t easy.

That said, I also lived alone and went over 8 months without seeing another person in the flesh, which is unlikely to be the case for younger people.
