Adapting

China's elderly population is exploding. By 2050, forty percent of the country will be aged over 60. Will they be able to cope? In Adapting, the first of a two-part series, Kong Fenglian helps residents adjust to life in Happiness Home, an old people's home in the suburbs of Beijing. Meanwhile in Shanghai, feisty TV agony aunt Bai Wanqing campaigns for greater awareness of Alzheimer's and advocates a new lease of life for the city's over-sixties.
