How can you spend your spare time doing something useful? Renato Grbic is a burley tattooed restaurant owner. Fifteen years ago he was fishing in the river Danube when he saw a body fall into the river from the nearby Pancevo bridge in Belgrade. He helped the man to safety and decided then and there to try to prevent other suicide attempts. He has saved 25 lives since by regularly patrolling in his boat under the bridge. Not all have kept in touch but one 18 year old who threw herself off the bridge after a row with her parents has since invited her rescuer to her wedding.
