Watch male lions they sleep when they want, laze about all day until they need to eat. Or you can be a deer caught in the corporate wage slave, alarm clock prisoner headlights.

Artificial light has a huge effect on drowsiness for me. This is quite noticable when I am out in the woods, camping in a tent. After sundown, I have about an hour left before I get so drowsy that I cannot keep my eyes open. Back home, indoors, I can stay awake almost indefinitely.

What about female lions?

Watch birds they fly when they want. Or you can be a slave worm bound to the earth. The choice is yours
