My biggest pet peeve is that it ignores the role technology (in the form of artificial light and comfortable indoor space) completely subverts our natural sleep cycle. It's a lost battle.
Better to accept that we're in an artificial state our whole lives and do our best to adapt to it. What I'm trying right now is a good melatonin supplement every night to counteract the unnantural stimulus, plus a magnesium supplement, and a lot of daytime exercise. This routine has gotten me from 6 hours of anxious sleep to 8-9 hours per night plus the occasional nap. And I feel great.
