The lad's fine, Bonzo. Little kids bounce quite well! Just a graze.

Good luck to her, Bill. I still have my doubts.

"Would any of us really expect an athlete to risk serious injury for Olympic glory."

Whilst we shouldn't expect it, the fact is that they do it in many sports, Olympic or not. The skateboard and BMX freestyle both looked extremely dangerous to me. Boxers take risks every time they take to the ring. Huge great big rugby players cheerfully crash into each other at great speed. Ski-jumping looks pretty dangerous to me. Heading a football has been demonstrated to significantly increase brain damage that shows up in later life. We've seen some very nasty cycling spills both on road and in velodrome. And so on.
