The problem with your cut off of "no comorbidities" for under 65s is - if it includes high blood pressure, the definition of co morbidity is so loose that the filtering becomes a clinically unjustifiable haircut of the true numbers of dead.
Most people with high blood pressure live completely normal lives and will do so for 30 or 40 years - it's not a disease which we see killing people in icu. Why exclude them other than to be shocked at how few healthy people have died. This is just fiddling stats.
Minority populations are especially affected. Whether genetics deprivation/diet or lack of vitamin D - "Western" lifestyles disproportionately cause diabetes and hypertension for those who have moved to this country from the global South. These diseases are extremely common even in people in their 40's.
The most deprived 20% are 3x as likely to die as the richest 20%. This Health inequality is true of most disease but covid amplifies the effect of inequality.
We could say when you look at rich white people under the age of 50 no one died. What's all the fuss about. It's probably what most Tory MPs are thinking when they aren't counting the reduction in pension payments accrued from killing the elderly.
See multiple Telegraph headlines.
The final part of the story that we can't provide anything other than emergency care to prevent loss of life or limb for young fit people when hospitals are full of patients with covid. Though we seem to have weathered the storm this winter we now have an almost insurmountable backlog of investigations and treatments. No doubt many otherwise well people are going to die on waiting lists.
