I'm (unfortunately!) not 20. I'm describing the sum total of all interactions, not just my own personal preference. I don't believe that "spreading the virus to people who are more vulnerable" is a meaningful concept for coronavirus. If you're immunocompromised (as, for example, my uncle is) then the outside world is now effectively a poison cloud and remains so regardless of what other people do in all realistic cases. It's theoretically possible of course that if everyone else isolated as well the virus could die out, but post-April 2020 this became a 'frictionless plane' style scenario that couldn't actually exist in the real world.
