Money? Who thinks about that?

This is an interesting article I came across http://blogs.bnet.com/bnet1/?p=1455&tag=nl.e713 that reminded me of the original which I'd read some time ago - the bnet article summarises it but doesn't do it justice - I'd recommend the full article at http://www.newscientist.com/article/mg20127001.200-why-money-messes-with-your-mind.html?full=true for when you have a few minutes.
