Bob Kuhn - Shaking up his World

In 2006, when he was 53, Canadian lawyer Bob Kuhn was diagnosed with Parkinson's. In May this year he set off on a trip to 16 countries to meet others with the disease, record their stories and, he says, shake up his world. He talks to Chris about the way different cultures approach Parkinson's, and says NZ - along with other developed nations - could help improve the lot of millions of people with the disease who are going without treatment in poor countries.
