I've always just blamed it on insomnia, but I wonder if this is part of the root cause.
That and 24 hours just doesn't seem like enough time to accommodate our circadian rhythm... not as in we're too busy to squeeze it all in, but like being conscious for long enough to actually be tired enough to sleep soundly, then do that for a full 8 hours, would take like 32 hours total. Being that we're stuck in a 24 hour cycle, sleep is the easier chunk to sacrifice.
...or mandatory chunk to sacrifice if your insomnia is as bad as mine...
WTB some magic thruster to face against the Earth's rotation, and slow that bitch down by about 25%.
