In the US, of people aged 20-44, "only" 2.0-4.2% are admitted into ICU, significant, but making up only 12% of the ICU admissions, and 20% of the hospitalizations. [1]

Correction: 11.9% of people in ICU in Italy are 19-50; 51.2% are 51-70; and 36.9% are > 70 [1].

About the only place I’ve seen where rational talk is allowed without getting flame to death is /r/covid19.
Hacker news, unfortunately, appears to have devolved into yet another place full of panic stricken people.
I'm happy to defer to actual stats if you have any.
Page 5 of the recent well-respected Imperial paper on modelling approaches to managing the outbreak has statistics on hospitalisation that I imagine are the current best estimates.

For example, 3.2% of cases aged 30-39 require hospitalisation. Could that rise to 40% after triage? I'm not sure, it seems high, but it depends on what pressures the system is under.
