Well, when I told my doctor I'd hurt my wrist falling while teaching myself to Electric Mountain Board he called me an idiot who should be old enough to know better. I'm 45.
For what it's worth I've been old enough know better for decades. I'm not letting that stop me from doing whatever the hell I want. So if you see a too-old guy on a skateboard with a white dog, be nice, it's either me or another idiot.
