Is it *really* worth taking the risk of getting C19 just for the purpose of “staying sane”?
I'm really, genuinely not in the slightest bit bothered about getting C19. I might even have already had it. The death rate for my age group is very low. Odds on it would just be an unpleasant couple of weeks. Unless there is a big change in the death rate, that isn't going to change, and because fear is innate rather than rational nothing anyone says is going to change it. You may get people to agree to measures to protect others, but I am not a germophobe in terms of myself and that will not change, at least unless there is a major change in my general health e.g. requiring me to take immune suppressing medicine.
I take a bigger personal risk when I go rock climbing or scrambling than I do taking a train at present (not that I am doing, for the protection of others).
One thing I find hard is that some people don't accept that that is the position of quite a lot of (particularly younger) people, and that any actions they are taking are done either because of altruism or because of fear of enforcement or the judgement of others. Probably a bit of both.
But talking of "staying sane", yes, it might be worth it even if high-risk, because people in a genuinely poor mental state (rather than just a little stir crazy) may be a suicide risk.
