Cool millions..

51 billion dollars to stage the Winter Olympics seems like a lot of money to me.  I read that there's 5000 competitors, and although its not a very scientific calculation, that's about 10.2 million dollars per person.  That can't be right can it?!  Even if I've cocked up the number of zeros by 1, that's still over 1 million per person.  I hope they have a good time.
Luckily for the UK, London 2012 only spent 13 billion which is looking like a bargain.
