I am sorry, but I still disagree.
Just, because natural adaptations to environment do happen, doesn't mean we should just give up. In fact, I would argue the oposite. We owe it to our kids to make sure they do not get bad genes.
And modern medicine makes this much worse. Since, we can support much more sick people, this is literally unsustainable process, because every sick person who does manage to reproduce thanks to insane drugs will have even sicker kids who will need even more drugs to survive.
