In the third of her interviews on the concept of renunciation, Ritula Shah talks to Dr Michael Irwin about the idea of renouncing life in old age or when faced with a terminal illness. Dr Irwin is a retired GP who campaigns for voluntary euthanasia and has accompanied people to the Swiss clinic Dignitas when they have chosen to end their lives. He talks to Ritula about his belief that people should have a choice as to when and how to die and about his thoughts on the end of his own life.
