Why can’t we go to sleep on demand like how we are controlling other parts of the body?

Question

We can stop breathing when we want to. We can also “tell” our body to do what we want such as moving, holding, typing, etc. So why can’t we just “tell” our brain to go to sleep immediately instead of having to wait for it to fall asleep.

Answer 1

Maybe it was possible in the past but everyone who had that ability got Darwin’d out of existence. Like maybe they enjoyed sleep so much they abused it and left themselves either malnourished or vulnerable at the wrong time and then eventually there just weren’t any of these voluntary sleepers remaining.
