Yeah, or does stupid stuff not caring and accidentally takes something too far. When I was 19/20 I used to ride my motorbike on highways in the middle of the night as fast as I dared when I was in a bad mood. Sheer stupidity.
Back then I never could have imagined all the awesomeness that I have experienced in the last 14 years. And it all changed very quickly. It's such a waste to never know.
