The replies to this are interesting. I suspect most people vastly overestimate the risks of catching COVID given *any one* activity (e.g. going to the grocery store once) but then fail to consider how much the risks accumulate when you're performing these activities *repeatedly*. https://twitter.com/meganranney/status/1299129806672592896

I'm guessing in my pre-COVID life, I was doing ~35 activities a week that would now be considered at least medium-risk. Most of these are boring: going to the office, riding the subway, eating meals in restaurants, etc. I'm guessing most other people's numbers are similar.

Even if the risk associated with any one activity is just 0.05% (1 in 2000), I'd have a ~60% chance of getting COVID if maintaining this pre-COVID lifestyle for a year. Actually, maybe a bit less because the risks are likely somewhat non-independent, but you get the general idea.
