50-year-old Andy Macdonald, Britain's oldest competitor, participated in the Olympic Qualifier Series first leg in Shanghai. Despite his age, Macdonald takes pride in still competing for an Olympic berth among younger athletes including 16-year-old Chinese skateboarder, Chen Ye. Macdonald and South Africa's veteran skater, Dallas Oberholzer, both prove that "old dogs can learn new tricks" in the sport.
