Q 25 What's the reason you jump?
...
But when I'm jumping, it's as if my feelings are going upward to the sky. Really, my urge to be swallowed up by the sky is enough to make my heart quiver. When I'm jumping, I can feel my body parts really well, too - my bounding legs and my clapping hands- and that makes me feel so, so good."

Q 45 Why do you enjoy going out for walks so much?
...
" The reason is that when we look at nature, we receive a sort of permission to be alive in this world, and our entire bodies get recharged. However often we're ignored and pushed away by other people, nature will always give us a good big hug, here inside our hearts"
