I find it fascinating that DST works. It works because we are conditioned to a nutty locked cycle.
We say, "school always starts at 8h. It has always started at 8". This ignores when daylight is and isn't.
We say, "the drive-in-movie must start at 21h because people must be home by (theoretical) midnight", rather than, "the drive-in show starts 45 minutes after sunset".
I appreciate time more on an isolated farm, or on a cross-country bike tour, or a multiday canoe. At an equinox, you get 12 hours of sunlight. That is invariable. If you waste the first three of those sleeping (because you follow the mandate that you must stay awake five hours after the sun sets), you are a slave to your wristwatch.
Growing up, my family would sometimes set our clock to reflect "honest-to-god noon" for our longitude (that even varies through the year compared to clock-time noon, but you can come up with an average 'real time' for your longitude). Most people today are far removed from noon being the exact middle of the day, and midnight the exact middle of the night.
It seems to me (and I've read concurring studies) that the average westerner is critically sleep-deprived. Doing anything useful? Not that I can tell... just following the rules that say, "must stay up for TV till midnight, must get up by 6 to commute". I think it keeps people weak, whiny, and irritable. When I bike-tour, I get 10-11 hours of sleep a night, and it really makes you happier, stronger, and healthier.
(I think this is my hundredth post. I just want to acknowledge this fine site, even if it does keep me up after dark too often
