I don't think that's necessarily true. Some might, while some might not. Again, just like with anything else in life, it depends on what one uses it for, what one gets out of it, and what issues one might experience--it gets balanced and then a decision is made. Sure, not everyone pays attention to all of that or sometimes really any of that, but that's far from simply overgeneralizing to say that no one cares and they all do it just because (even if some might).You're missing the point that they would use it regardless.
