I think most of us enjoy watching extreme sports in small doses.  That reason alone is why the X-Games on ESPN are still alive and kicking.  BMX biker "Special" Greg Powell landed the first ever Special Flip, a move he created himself.  What exactly does a special flip involve?  Powell has to jump off his bike in mid air, do a back flip and land back on his bike all while flying over a 32ft gap.  Pretty amazing.  Do I even need to say don't try this at home?
