My sorrow and sadness from being in a place where I can't walk to go do things is substantially worse than places where I can.

I can walk in cities.

Why can't you walk outside of cities? At least where I live and mostly travel, northern Europe, walking outside of cities is easy.

I'd argue that's only true if you ignore loneliness in areas outside of cities. I would have a hard time living somewhere that I didn't run into people.
