For Max Burt, November 2nd 1999 was a life-changing day.
He had recently married and was about to move into a new home with his wife. He had also just resigned from his job as Head of Planning for a major London advertising agency to start a new business.
Then, on his usual route home from work that day, he was involved in a collision with a fire engine answering an emergency call.
The accident left him with severe head injuries that mean he is unable to balance, or walk, or talk as before.
