Wouldn’t that be interesting? I know when I got COVID, the one time I got it in the last 4 years, it took me out for 3 straight days. I couldn’t imagine trying to do well in a debate while inundated with all that comes from COVID.
Since the vaccines started becoming standard, infection rates have normalized and the current strains are much less harmful than the first (if vaccinated, if I recall). It’s possible that COVID could mimic similar symptoms to a cold and drastically influence debate performance. It would definitely explain the senility we witnessed.
Bottom line is that Biden is old as fuck, we know, but the dude bikes and exercises while constantly barraged by people shouting he’s “too old” and “should drop out.” I think I would bomb a debate with all that shit, too! Add COVID to the mix and I’d probably want to die rather than debate a serial-liar.
