That´s the difference, for skydiving or base jumping there´s no other option to do it safer. If you like it you must assume that risk
Motorcycling on the other hand can be done on a much much safer environement, so the only reason to assume such a high risk for your live is proving how big are your balls
That´s the reason I wonder if it´s a matter of big balls or small brain as it´s completely unnecessary, if you enjoy bikes and racing you can do it without those risks, but obviously it is not a matter of proving your talent. Talented riders race at very different tracks
And plese note I´ve never feared assuming risks, I´ve been MX rider for around 10 years, broken several bones and ligaments and I´ve been operated twice and neither of those injuries or operations stopped me from practicing MX, but in my eyes there must be some reason to assume any risk, but if you can do the same without risking your life...
Ok the feeling must be different between buildings, that´s the only reason I wonder if it´s a matter of bravery or madness, if not I´d assert they´re all mad
