Only humans control their sleep
There is no other mammal in the world that knowingly and willingly delays sleep or shortens sleep. Humans are the only animals that do this. In fact, we have some of the shortest durations of sleep of all of the mammals. Research suggests that’s likely because we benefit greatly from being awake for more hours than other mammals. We build things, do things, invent things…So if you feel your ambitions and goals keep you from sleeping, that may be evolution at play.
