One, maybe unexpected, thing that I will take from these Olympics is the spirit of competition. Watching the Football Community Shield yesterday I was immediately frustrated with how childish everything was, abuse towards the referee, each other etc. etc., both from the players and the fans. These are things that are pretty rare in the Olympics, even in the football tournament - all the athletes are there to do their best and the fans cheer them on, but when everything's done and dusted you see hugs and congratulations all round.
I still like, and will watch, Football and other sports, but they could learn a lot from the last couple of weeks.
