Life has inherent risk. When I drive my car I fasten my safety belt. I keep good tires on the car and don't drive drunk. I don't drive too fast or recklessly. I do all of that to mitigate the risk in the hope that I will not be one of the 70 people killed EVERY WEEK in auto crashes, but I still get in my car and drive. I accept that risk as part of living. As far as CV goes, I think it's great to mitigate the risk. Are we going too far? Probably. We'll see. North Korea and Zimbabwe have no CV cases because, basically, no one goes into or out of those countries. Should we be jealous of them? Hardly.
