I said it before months ago, and I'll say it again now:
I am a semi-elite runner. I know of at least two running buddies (both of whom are way, way, fitter than you think you are), both my age, who had Covid. The first is an idiot who got it at a party and was sick as hell for a week, and had lingering weakness for over a month. The other was also extremely sick for about two weeks and ended up with fears about heart problems, going back and forth to the hospital for various tests. He is just now, five months later, back to about the same fitness level he was at before.
I don't care who the hell you think you are, or what you think your statistical chances are of getting sick; if you're not afraid of contracting this disease, you're a certified, grade-A dumbass. If you're scared of the vaccine but not the disease itself, then you're even dumber.
