It is next to impossible trying to find an exact number of young and "perfectly" healthy people who have died from Covid. Call be skeptical, cynical, whatever, if that number statistically significant it would be all over the news. Best I can find is they consider under fifty as young. According to a couple articles I read, which are now a few days old the number was under a thousand and nowhere can I find an exact number of that group had zero preexisting conditions or any health issues whatsoever. Safe, real safe to say that the only real at risk group are the very elderly over 80, over 65 with health issues, and those younger who have compromised immune systems due to any number of things, obesity, cardiovascular, diabetes, etc. For everyone else this is nothing more than a bad cold and that's if you have any symptoms at all. Most, like nearly 80 percent have no symptoms or symptoms so mild they are dismissed as having a bad hair day. Conclusion by any reasonable person would be there is virtually no risk to young perfectly healthy people. Outliers for the young person who happens die are as meaningless as the old fat guy who survives. No person looking to do an actual threat analysis would even count those at all.
