James is a distant relation and came to stay with us in Lincoln. He is eight years old and has type 1 diabetes, which means his pancreas doesn't produce any insulin. This can seriously damage the body's organs over time.
It is a condition that affects 29,000 children in the UK, and there is no cure. However, Juvenile Diabetes Research Foundation is working hard to find one. James is running the equivalent of a half marathon, which requires running a mile a week at school and then the last mile at Wembley Stadium.
He wrote: "I wanted to show people that having diabetes makes you no different from everyone else. I wanted to raise money because I thought it would be a good idea to raise money and find a cure for type 1 diabetes. We did this work at school for Martin Luther King Day and we had to write about our dreams. I had a dream that one day they would find a cure for diabetes and you could live without having to give injections or have a pump, and you could have an artificial pancreas."
He is a great lad and has a clear future as a fundraiser. JDRF encourages people to raise money for it by taking part in events such as the City of Lincoln 10k, on 17 April. The University of Lincoln takes a lead in research and last December its School of Life Sciences received £50,000 from the Freemasons' Grand Charity to conduct research into the rogue cells that destroy those producing insulin. Every little, or even a lot, helps.
