AFTER laying unconscious in a ditch for five hours, awaiting rescue following a car accident, Martin Grimmer was lucky to be alive. Left with severe injuries despite months of hospital care, Martin faced one of the biggest challenges - rebuilding his life, becoming self-reliant and returning to work. Years later, the 36-year-old has done just that. Now his story forms part of a new book called Overcoming Barriers. Martin's life forms one of the six personal stories about people who have overcome severe disabilities to find work again, with the help of The Papworth Trust. Martin, from Wisbech, who was a builder, nearly died in 1994 when his car ended up in a dyke off a fen road. He had been driving home from work in St Neots when his car left the A47 between Thorney and Guyhirn. As he was not wearing a seatbelt, he was thrown from the car into a field. His problems at that time had only just started. As the ditch was so low it was out of the vision of passing motorists. Martin lay unconscious for five hours before he was found, and when he was discovered his injuries were terrible - he suffered severe head injuries after being flung through the windscreen. Martin was on a life-support machine for three weeks and in hospital for six months before he was discharged in a wheelchair. After years of rehabilitation sessions, he was back walking and was referred to the Papworth Trust and was given a route back into work. The trust suggested a three-week trial placement at a tree and plant nursery called Choice Landscapes. Today he works there and now walks and drives.
