No sweat. You are, of course, correct. Darwinian evolution does not address the survival odds of individuals within our species, despite the "Darwin Awards" and all that.

I can relate to your experience. It can eventually get pretty annoying when you see people constantly and cavalierly misusing or ignorantly mangling something you have acquired some expertise in. Wasn't Darwin himself also rather taken aback by some of the uses and debate surrounding his seminal work? I can't remember, but I think I recall something about that.

My own related personal pet peeve is with those who attempt to over-generalize the theories of evolutionary biology outside their proper realm of biology and impose them upon the social sciences, i.e., as so-called "social darwinism."

As to our dependence on modern medicine, my thought is that many more may suffer some impact on their quality of life than will actually die from its absence after a total collapse.
