Ah, the indomitable human spirit! Love it.
I think we all know the feeling: you're SO keen to do something, you put your hands over your ears to block out all the "danger, Will Robinson's" and go for it.
Never mind. As my former boss used to say: "It's all good, clean fun" :)
And you know what? I think we're most alive in those moments.
Disclaimer: there's risk and there's RISK. If deep down in your gut you know it's a dumb idea, DON'T DO IT. This guy always had a bail out: he could just get off the bike.
