Sometimes we do things then look back and wonder who we were when we did them.
This appears to be the case with a 17-year-old Chinese boy who reportedly decided that he would not give his right arm for an iPad 2, but he would give his right kidney.
I know, I know. It doesn't seem entirely sensible. On the other hand, you can live quite happily with just one kidney. It's a lot harder with, say, just one foot.
