Credits to Stefan Yazzie Herbert for bringing this important subject to our attention in an understandable and animated fun way. And, thanks to Jan Denneman for explaining good light and biological darkness.
Also, the sign in Stefan's room is cool saying; more lights please.
What comes to my mind is; stay hungry, stay foolish. Or, this message is so clear and logical, it should make people aware, change our behaviour regarding daylight and let us act: use more & better light indoors.
