if there was a burning building with 2 people in (one 21 and one 81) and you only had time to get one out who do you pick
That's exactly what was going through the minds of many doctors throughout the last year, indeed plans were drawn up on who to treat, who to let die should resources get to that point and some hospitals came very close to closing their doors to people. As it stands we managed by in some cases shipping patients hundreds of miles to a hospital with capacity - and that's DESPITE lockdown!
I'm sorry for your friend and you are right to be angry about that, but your anger should be directed at the government for not putting restrictions in place SOONER - lockdown SAVED lives, but if SAGE had been awake at the start and we'd implemented border restrictions last February, coupled with other limited measures targeted against any cases that snuck in, we'd never have needed lockdown, the NHS would never have been stressed and life would have been largely normal for most of us.
