Would you maintain that attitude when confronted with your own or your loved one's diagnosis for something terminal and agonizing? Or is that cavalier, pretentiously "utilitarian" stoicism reserved for the young and invincible?

And even if you don't value your own health, substituting another warm body in place of a cold one does not undo the suffering caused by disease and death. All those people you don't care about deserve better than your "meh." And thank goodness we have so many people who disagree with it.
