A couple of years ago I worked on an amazing project with Michael Mosley, that tragically turned out to be one of his last. He was an absolute pleasure to work with, and this series brought out the best in him as a curious investigator. He was just as interested in people and their stories off camera. Its tinged with sadness, but 'Secrets of the Superagers' gets a release on Channel 4 on Monday (and subsequent weeks) at 8pm.
