When we lay down at night why our brain does not recognize it and make us fall asleep much easier? Interesting that we have control over so much things but not our own body.

We kind of can, bit it isn’t an instant thing. More like turning off the oven and waiting for it to cool down. We need to dim the lights, stop drinking caffeine (like 6+ hours prior), avoid blue lit screens, not try to solve problems, not be over-stimulated, not get under the covers where we also eat, work, play, and generally act very awake… There are other things that factor into it.
Why isn’t it on/off? What benefit would that be? If there are stimulating things around–light, predators, invaders–then being able to turn off in the midst of that would surely be used enough to be selected against, so the trait would die out pretty quickly.
