I like how you're ignoring the organ damage in even younger survivors like it's rosacea or something.
All evidence so far is that a small fraction of people sick enough to be in the ICU end up with some sort of non-lung organ involvement. The vast majority (>99.98%) of young (<50 years), healthy people don't end up in the hospital at all, let alone the ICU.

If this is the best you can do, you're grasping at straws.
