as we welcome the 2012 olympics..

"In athletics, if you come up against a particular high hurdle that you have to jump, you take a longer run! If you want to vault over it, you go further back. You do not try to lift yourself up over the high hurdle from which you are on the ground. The further back you go, the longer you run, and the momentum will carry you over."

-  Dr. David Martyn Lloyd Jones
