Actually, perfectly well. It's modern times. We optimize for long individual lives, not propagation of the species. As lifespans increase, so should efforts to avoid cumulative, damaging radiation.

Similarly, heavy meat consumption gave early humans an advantage, but you shouldn't adopt that caveman behavior for a 100-year lifespan - it doesn't "work" at that scale.
