in the process, ~.6-.8% of us, almost entirely over the age of 70, are going to die, if we don't take drastic steps to prevent them from interacting with the general population, which we seem to be unwilling to do.

it's not natural selection when you're talking about old people dying. natural selection has to do with reproduction, which they've already passed their ability to do. but, the development of new viruses is a very natural and normal response in organisms that are experiencing overpopulation. 

you're not helping anybody by denying the facts, which are uncomfortable, but need to be confronted and reacted to.
