Jumping, for kids?

After asking myself How do you jump?, I realised that my jumps are certainly much less joyous and frequent than they once were. I'm talking jumping metaphorically really, since broken toes, patella tendonitis and lame ankles (plus an extra 10kg) have entirely cramped my real jumping "style". Although even these are all treatable, and I'd love to once again feel the momentary elation of having to actually wait till I return to the ground. But I digress...

Metaphorical jumps in particular should be unencumbered by all my many reservations (ok, fears) about just about any change in my life. I've never been adventurous (ask anyone who knows me well, and I doubt that would feature in the top 1000 adjectives they'd apply to me. Try it in a sentence: "I can't believe how adventurous Bertie is" :) But is that "just me" or is it the me I believe myself to be? If I believe, really believe I'm a risk-taker, do I become one? Do I want to be? Is my cynicism about myself too ingrained?

Is the answer as important as the question?
