Probably false.

People don't find flimsy excuses to refuse conventional life-saving treatments, and non-conventional treatments can become conventional (say, antibiotics). This holds, though less so, even if the treatments cost quality of life and money.

I didn't start out liking life, but I seem to be very atypical in that regard (often suffer from anhedonia, for example). But it's more likely that I've moved away from the norm, not toward it, especially since I'm bad at distinguishing norms for X from norms for "X"... shudder

Scary. Someone please disprove this.
