If I'm interpreting the news correctly it seems that even a lot of not-so-old people (30 and up) seem to be ending up in intensive care with some frequencey, but that aspect of it (bad pneumonia) just isn't deadly in healthy people under 50 if you are given quality care. Elderly people seem to suffer myocarditis or failure of other organs.

What's worrying about that though, is that the high survival of healthy people under 50 seems to be conditional on the availability of ventilators and ecmo. Few countries can guarantee that in all scenarios.
