JK Rowling and Multiple Sclerosis

I mentioned to Mom once that on JK Rowling's website links, she links to the British MS Society. I always wondered what her connection to it was. I came across this interview in the UK Tatler magazine with Rowling where she talks about her mother's battle with multiple sclerosis. I thought you might find it interesting:

A tear slowly trickles down JK Rowling's cheek. She is sitting in her large and comfortable drawing room in the Morningside area of Edinburgh. It is early afternoon; sandwiches and chocolate cakes are left untouched on the coffee table as she painfully recalls the most traumatising moment of her life. It was the day her mother, Anne, died aged 45 after a 10-year battle against multiple sclerosis. A small part of her agony is that her mother never knew she was writing Harry Potter, let alone that she would become the most successful author on earth. "The night she died I had been staying with my boyfriend's family, the first time I had ever spent Christmas away from home. I had gone to bed early, ostensibly to watch The Man Who Would Be King, but instead I started writing. So I know I was writing Harry Potter at the moment my mother died. I had never told her about Harry Potter."
