From what I've seen, there just aren't, especially among the fit, young, and skinny with no comorbidities.
If you're young/fit/healthy/skinny (whatever you want to call that), then getting hospitalized would be along the odds of getting struck by lightning.
Change my mind.
P.S. This is by no means to take away from telling people to get vaccinated, as I believe most should immediately if they haven't already. But to the earlier point, not pushing health and fitness was a HUGE miss (and still is), especially before we had a vaccine. Even after having a vaccine, it would keep a huge percentage of people out of the hospital.
