Sadly I'm really not in the best shape to jump on a push bike and throw myself down a steep slope. For something to be worth doing just for the thrill its first got to enjoyable

And I guess if all your seeking is the rush then there's also things where the odds are certainly more stacked against you than rock climbing... I'd imagine Russian Roulette would be pretty intense

Its also the first time I've ever heard anyone call the seats in an Impreza comfortable! Functional would be a better description.
