Bono is apparently more crap at riding a bike than I am:

On the day of my 50th birthday I received an injury because I was over indulging in exercise boxing and cycling, which was itself an overcompensation for overindulging on alcohol coming up to the big birthday. I promised myself I would be more mindful of my limits, but just four years on, it happened again – a massive injury I can’t blame on anyone but myself, mainly because I blanked out on impact and have no memory of how I ended up in New York Presbyterian with my humerus bone sticking through my leather jacket. Very punk rock as injuries go.

Recovery has been more difficult than I thought… As I write this, it is not clear that I will ever play guitar again. The band have reminded me that neither they nor Western civilization are depending on this.

The whole thing is on an alphabet riff; scroll down for X for the inevitable X-ray of his repaired elbow, which looks even scarier than my repaired femur.
