Contributor(s): Donna Thomson, Geraldine Bedell | Donna Thomson will discuss her book, The Four Walls of My Freedom, which describes her family's experience of coping with her son's cerebral palsy. Her own encounter with adversity takes on new meaning when viewed through the lens of Professor Amartya Sen and other philosophers' roadmaps of how to realize a good life against all odds. This lens includes not only people with disability, but also the enormous generation of post-WWII Baby Boomers who are beginning to sense the health care crisis that is looming as they deal with their own aging and increasingly infirm parents. Geraldine Bedell is an author and critic. She is currently working on developing a new project for mumsnet and is the founder of the website Agebomb. She has been a writer The Observer and The Independent on Sunday. She has also written for The Times, Telegraph, Mail and Express, and for many women's and general interest magazines.
