"Legalize Siestas" sounds funny but I think it would change all our lives for the better. It's likely never to happen under our current economic system though.
I find Siestas the absolute worst thing possible for my sleep schedule. Even 20 minutes of noon naps completely nuke my sleep schedule and it takes days to make it normal again. I actually tried Siestas pretty hard for at least 2 years when my insomnia was worst, but eventually I realized without naps my sleep schedule is much more predictable.
