For me, the effort of going somewhere to exercise is a big impediment, and I’m self-conscious exercising in front of people. The low barrier to start a daily workout wins, hands down.

Others find camaraderie just having other people involved in the same process, or really enjoy the variety of machines and options of a well-equipped facility.

You have to figure out which type of person you are. The most important thing is just to do something. (Unless you have specific, Jason Momoa-type goals in mind)

Everyone who survives will be immune.

That’s the whole logic. It was awful enough with Covid’s 1% mortality. Measles only kills about 0.1%. Bird flu kills 90-100% of infected birds and 50% of infected humans. And there’s plenty of lasting/permanent deficits short of literal death. They’re psychopaths.
