My spouse has no relevant health complications, and has been knocked absolutely FLAT from this. We didn't have to go to the hospital, there were no ventilators involved. But now, almost 4 months later, and they struggle to walk 100 paces, to go upstairs, etc. The risks are more than dying vs not-dying.
