This is supporting a cause close to my own heart - wheelchair sport.

My late Grandad was a volunteer at Stoke Mandeville, which was the birthplace of the Paralympics. He gave up so much of his spare time to support Paralympic sport and despite a terminal cancer diagnosis in 1995, managed to get a spot as a Paralympic Official at Atlanta '96, which was his proudest achievement, and almost certainly kept him alive for a lot longer than expected. I still have three commemorative medals from his time there.
