So much of childhood is laid out to prepare you for adulthood. Sports instill teamwork and respect for authority. School programs you for the workforce. Chores, then summer jobs, and then eventually job-jobs, teach you the value of a hard-earned dollar, or something intimidatingly folksy like that. But forget all of that you ever jump off of a large rock (perhaps even a cliff) into a body of water when you were a kid? Nothing trains you for the real world of risks, peer pressure, exhilaration, fear, and courage like that. Life comes at you fast, and so does the cold smack of the surface.
