When I heard that West Ham football manager Glenn Roeder, 47, had suffered an aneurysm - the swelling of an artery in the brain - I knew exactly what he was going through because I survived one a year and a half ago. Now that I have recovered, in a strange way I feel grateful for the experience. I know that may sound odd, but it has enabled me to see with new eyes. As a photographer, finding a new perspective is like a gift. Since the aneurysm, I have produced the best work of my career.
