Webs tifón we usted to Liverpool there

What if we used to live there?

I heard somewhere that it's actually a 36 hour cycle if kept out of daylight, but idk.

Imagine if we had exaclty a 24-hour natural rythm. Instead of the 25-hour rythm making us re-synch by an hour each day, we'd stay naturally in synch. But then when traveling several time zones away, instead of taking about an hour per day to synch to local time, it would be an enormous hurdle.

Maybe we are the aliens that killed the dinosaurs
