interestingly enough, i feel this same way about you and your claims to "take offense."

clearly, comorbidity is an issue, but you seem to ignore cross correlation to senescence etc. as thought the two are somehow independent variables. they are not.

you made this specific claim:

"Your assumptions for why flu is supposedly high risk for the elderly are wrong. Advanced age is heavily confounded by lifestyle factors, which means the effect of immunosenescence is being overestimated by basically all doctors and scientists."

and it is neither particularly accurate except from a certain angle nor particularly germane.

clearly, covid risk amplifies greatly with age even with zero comorbidities.

you seem to be engaging in projection on failing to see the big picture.
