Thanks for taking the time to reply. I've thought about what you wrote, and came to a realization that the answer to the question:

> What would it take for you to find walking interesting?

Is... no longer feeling like everything is slipping away or collapsing around me; no longer being stuck treading water. It's more of a therapy problem than HN-on-exercising problem.

I never particularly cared for nature, and still don't - except at the biomolecular level, where life fuels my dream/curiosity of functional nanotech. But this is separate to enjoying a walk down the park, or a hike with friends, which I realize I don't mostly because of the internal stress about not doing something better with that time. The few moments I take the plunge or get forced into a situation where I can't do anything but enjoy the time outside, after initial anguish they become relaxing. But I can't make myself engage in such things on my own, not without having some convincing excuse for this helping to get me out of my various predicaments.
