Like so many who serve, Falklands veteran Geoff Stear took trauma away with him - in his case a very particular reaction to the smell of meat. It was so powerful and debilitating that it made his life almost impossible, leading him to injure himself and endanger others as he tried to get away from the perceived danger. On several occasions it left him hospitalised – once with a broken neck - with no recollection of how he had got there. His life hit rock-bottom, until a chance meeting with a stranger changed everything.
