And also possibly getting the most sick you'll ever get in your life, with possible long term effects. Like how exactly does that sound like a reasonable risk to take so you can go to the gym?

I agree completely. It is very easy to dismiss the problem if you are young and you only look at your individual risk. But if you look at society as a whole, the problem is significantly more complicated.

Odd. I see mentions of that literally every time someone brings up the large differences in mortality by age.

It's possible that we mostly exist in different filter bubbles though.

Possibly.. but even this thread I was felt like there were more mentions to just purely stats of IFR by age group as if that was all that matters and they were very active in this thread.

It's good to know it's being brought up when people mention IFR of age groups as if that "proves" we shouldn't worry about it.
