Thanks for your comment, Dave. My example with motorbikes was just to illustrate a statistical falacy. I know well how dangerous motorbikes can be. Many years ago I played in a rock band and after only two months of practicing we lost our drummer in the accident. Three weeks later the landlord of my student appartment crashed too (leaving behind a wife and two young girls). I lived in that house for another 6 years and watched them grow without a dad. After attending two funerals in less than a month I said; I'm not finishing like this. Even though my father is an enthusiast and we have motorbikes at home, I'm not touching them again.
BTW; I like the ideas in your article. :)
