All of the above is so true, I watched a programe on the goggle box several months back and It basically stated that there are two main groups of people those that sit at home and do only "safe things" and do there damdest to bugger up everybody elses life because they are a bit sad and the ones who go seeking adrenaline rushes ie: motorcycling snowboarding skydiving hangliding climbing etc, you get the picture, aparantly this activity releases some natural drug in the brain (can`t remember what it is) but this gives you a natural high and generaly doesnt turn you into a saddo because you enjoy life so much you don`t give a tosh about what anybody else is doing.
