Or, in a sporting context, at what point does the satisfaction of being able to compete in a range of disciplines become lost in the desire to be the best in just one?

For Scott Frew, that point has finally arrived. As a teenager, he represented Scotland at age-group level in both rugby and basketball, showing such promise that he earned a scholarship in the United States. There, having discovered an aptitude for track hurdling, a series of poor decisions and injuries led him to return home, whereupon he was catapulted into contention to play handball for Great Britain at the 2012 Olympics. That he failed to make the final squad for London still rankles, even though he was named as a reserve.
