The Rio Olympics just concluded, and for me there was one “Aha” moment – Joseph Schooling. Rings a bell?  To my fellow Singaporeans he’s more than a hero and a household name. To the wider world – Why? 12^th August 2016, he struck gold in the 100m butterfly, beating Michael Phelps by half a body length.  Phelps – a name the world has known for over an Olympic decade.  The largest winning margin since 1972!  The two previous Olympics saw Phelps win this event. How could that have happened?
