Professor Sarah Harper is discussing the power of social networking on high life expectancies in CNN’s special report Vital Signs with Dr Sanjay Gupta.
Vital Signs explores health stories from around the world, giving a global perspective on how health issues are detected, treated and handled socially. "We know that in many ways, this can have almost the same effect as living a good life, eating well, not smoking, not drinking too much alcohol," said Harper.
The programme ran on CNN international and is currently airing on CNN Domestic.
