Today’s offering is dedicated to all those out there who, now that you are a grown up (with a proper job and everything!), find that it significantly fails to live up to the hype. So for example, that few quid that you had carefully put away to get yourself those much needed new climbing shoes, miraculously converts itself, through as yet unexplained laws of physics, into a new battery for the car. Is it acceptable to blame Brian Cox? I’m going to anyway. Although he’d probably have to go to the Atacama desert to move a small pebble to explain his innocence.
