Yep, there's not really any animal that "sits" for a long amount of time.

You're either up and moving around, sitting for maybe five minutes, or just full on flopped on the ground.

Sitting for 8 hours while being physically inactive but still alert just isn't natural for really any living thing. Even ambush predators are laying down while they wait.

That's what great about work from home.

I bounce between laying on a couch, sitting in a comfy chair, an ergonomic office chair at a desk, or standing at a counter.

If I did any of those things for 8 hrs straight, my back would be killing me.
