Call this old age, extreme edition: Eight players with 703 years among them compete in the Over 80 World Table Tennis Championships in China's Inner Mongolia. British players Terry, 81, who has been given a week to live, and Les, 91, a weightlifter and poet, are going for the gold. Inge, 89, from Germany, has used table tennis to paddle her way out of dementia. And Texan Lisa, 85, is playing for the first time. 'Ping Pong' is a wonderfully unusual story of hope, regret, friendship, ambition, love - and sheer human tenacity in the face of aging and mortality. By Hugh Hartford and Anson Hartford.
