“[Our evolutionary ansestors] made an effort primarily aimed at obtaining food, for one-third of the day. They slept for one-third of the day, and spent another one-third on pleasures - eating, grooming each other, observing themselves and their surroundings, flirting, and sex.
If you take care of a dog, cat, hamster, or ferret - pay attention to how they spend their time. Start taking cues from animals other than humans - because they are our close evolutionary relatives, with nervous systems similar to ours. Have you ever seen a dog chasing its tail for eighteen hours a day? Have you heard of a rat or hamster that would willingly run on a wheel non-stop?” link
