Where wouldn’t we have all ages in ICU and easy to work out median?
I don't think it works like that.
Having had the misfortune to be a guest myself.
I'm told that the people who get put in the (limited and costly) facilities are those who have around a 50-50 chance of coming out alive.
If you have a hundred cases, and only room for ten of them, you will put your resources into those you are most likely to save.
Not those who are sadly beyond hope; nor those who are fit and cheery, chatting to the nurses and phoning Downing Street and are in no danger, but will recover anyway
So the young, and the very old, are likely to be under-represented.
