Cures? No. Stabilizes? Maybe.
I don't do much exercise. My job is very physically demanding, so at its core it's akin to... well, core exercises, I think. Powerlifting primarily, and a lot of walking. My sweatcoin app registers about 30000 steps on average, but since about half of it is underground where connection is poor, I estimate its close to the 35000 region. I also walk a lot on my own, primarily on weekends. I'm addicted to walking. The inside of my knees, some spots below the knee cap itch if my body doesn't think it walked enough.
I live in an urban areas, so there are no natural hikes for me to go on save for a building site about 2km from where I live. It's a "natural" hike in the sense it feels like walking through a desert. A desert full of cannibals because they stare at me passing by on my way to the hospital the same way women describe rapey guys staring at them.
But when I don't go to the hospital, there's another bike I take on a path towards the beach. It's about 25km long by rough estimate (I measured it using the ruler thing on Google maps). I take this hike when I'm experiencing a surge in seizures.
The mundanity of repeating the same movement a bajillion times combined with carryingy weight does seem to have a small calming effect, albeit it's also negated by the fact my legs beg for amputation.
