Look, it's a numbers game!
Statistically speaking, if even 0.01% of all humans were to suddenlt wake up with naturally blue hair one morning that'd still result in a hell of a lot of people with blue hair globally. But also, on an individual level: you, personally, would still only have a 1 in 10k chance of ever waking up with hair that had turned blue overnight.
Of course young people will die! This is statistically inevitable seeing how many people are infected. But also: it's still exceedingly unlikely to happen to any given young and healthy individual even if they catch COVID-19. So, being scared and panicky really doesn't help!
What does help is to follow best practices and guidance so as to keep the total as low as possible. That'll save a few young and healthy people. And a great number of less old and less healthy ones.
But, really, the young and healthy aren't dropping like flies. They make the headlines because - despite it being statistically inevitable - them dying is unusual even under these current circumstances!
