I think it's an age thing. When i was a younger lad and fit as a butcher's dog i would ride the hell out of whatever and whenever and didn't give a damn. After a few tumbles and seeing mates take the long ride to oblivion a feeling of self preservation started to gnaw at me. The thrill or bravado of riding through all weathers just to say "hey, i'm a Biker" starts to wear off as the bones start creaking and the butt starts aching. For sure, i still need the buzz but nowadays not as often.
