Will Liddell studied zoology at university before working on cotton pests in South America. He then changed direction, studied medicine, and eventually became a general practitioner. In this conversation we discuss how his many interests, including Neuro-Linguistic Programming, have fed into his clinical work over the years. Will also owns a farm and has an enduring commitment to environmental science and sustainability. We explore the idea of healing as something that applies both to people and the natural world.
