Oops

A Japanese biker failed to notice his leg had been severed below the knee when he hit a safety barrier, and rode on for 2 km (1.2 miles), leaving a friend to pick up the missing limb.

[...]

He felt excruciating pain, but did not notice that his right leg was missing until he stopped at the next junction, the paper quoted local police as saying.

The guy's from Hamamatsu. I used to read the blog of a guy who lived there, though he stopped posting shortly after his baby daughter was born. I wonder if he's still there. I wonder if he knows this guy :>
