When I was a young distance runner I was in such good shape that, when not tired from a workout, moving around the world was essentially effortless. Its kind of like playing a first person shooter and very easy to feel like your body is just some abstract tool. In contrast having a minor injury causing you to limp or something is very grounding, forcing you to focus on walking carefully and not have to hurry for anyone.

wasn't that a side effect of endorphins/runner's high ?

I believe it is a side effect of being in good shape.

They said when _not_ tired from a workout.
