This was near the end of my last season with the Shanghai Sharks’ junior team. I jumped for a rebound and landed on somebody else’s foot.

At the end of the canyon, we made our way on foot to the cave.

It's a big pestle, it stands just over a foot tall (about 35 cm), and the business end is a stone bulb, about the size of a cricket ball, and you can feel that it's been much used.
