I had never paid this any attention, but on a lark put a fiver on a horse yesterday...
First of all, I had no idea it was a gladiatorial event. But I think they said all the horses and jockeys survived unharmed.
Secondly, if you guys are wondering, the horse I bet on was the one who threw his rider right off the bat and then romped around in everybody's way for the rest of the course.
So not only did I lose my five pounds, but had to watch him gleefully cavort about for the rest of the way.
