Many good ideas but author too crazy about daylight. He probably doesn't know that in many parts of the world u can't wake up when its light and go to sleep when its daylight because its different each day.

So what u gonna say on that? It literally impossible.

I go to sleep at 3 am and wake up at 11 am and everything works the same for me. Just shifted time. Because body do not linked to the light. Some other parts are useful but thing with daylight is BS.
