I think we are.

I, for example, would have died at a very early age but for medical advances made shortly before my birth. That said, other "advances" contributed to my poor health as an infant.

Although I have since grown into a normal adult, I represent an example of somebody who wouldn't have survived to an age where such adventures would have been feasible. Reflection of this trend can be found daily, in people who indulge in self destructive behaviour and yet are saved, if not from themselves, from being a warning to others.

The trend of opposing behaviour that forms a basic part of humanity is just one result of the "saving" of less resilient souls and will, more than anything else lead to the downfall of Homo sapiens.
