I don't think that adventure has to mean climbing a mountain, or some other "extreme" physical endeavor.  I think it's different things to different people, but I do think it always involves pushing yourself to spend some time outside of your comfort zone, whatever that may be for you.

“Any coward can sit in his home and criticize a pilot for flying into a mountain in a fog. But I would rather, by far, die on a mountainside than in bed. What kind of man would live where there is no daring? And is life so dear that we should blame men for dying in adventure? Is there a better way to die?”

- Charles A. Lindbergh, Jr.
