World championship silver medallist Sharat Singh (middle) checks the grip of two Class XI students of St. Xavier’s Collegiate School, Calcutta, as they square up for a friendly arm-wrestling bout on Wednesday. The 40-year-old Xaverian went to his alma mater and conducted a two-hour workshop. Principal Benny Thomas advised the students to follow their passion just the way Sharat had done. ‘You must follow your heart.... It could be music or mountaineering or academics or photography, it’s best to do what you can do well,’ he said. A father of two daughters, the arm-wrestler is a successful businessman too. Passion could help 16-inch biceps crush 22-inch arms, said the 81kg Calcuttan who had outplayed an Ukranian and an Italian — above 95kg — to bag his world championship silver in Punjab.
