One advantage to be always moving, you seem to be perfectly in the flow of the day. One disadvantage, your body can only expend so much energy, and find yourself bone-tired.
There is something "clearing" about a total physical exhaustion. There is a certain joy in making it to the end of the day. Still kicking.
Maybe this kind of existence connects you back to the Neolithic past? It's a more primitive, primal way to live. And it's the simple pleasures that drive you forward: a good meal and a refreshing sleep.
Strangely to live so totally in a physical realm releases the mind to kind of float. You can actually imagine yourself floating above yourself and observe how a human exists. Interesting double-life!
And there is still enough energy to imagine other worlds and other ways to live.
