why do we pretend to sleep to fall asleep
@shanselman My guess is we pretend to sleep for cultural reasons. There is evidence biphasic sleep would be the norm for adults without electic lighting: https://en.wikipedia.org/wiki/Biphasic_and_polyphasic_sleep
The wakeful time in the middle of the night was a prime time for causing mischief, so there were social reasons to stigmatize being awake at night as a wicked thing.
Also for teamwork to be successful it helps if everyone is around at the same time.
