Something Understood - On Walking

What many of us take for granted as a rather mundane activity is elevated for others into a creative, spiritual or philosophical meditation. Drawing on the writings of a Buddhist monk, the artist Richard Long and the Danish philosopher Kierkegaard, among others, Melissa Viney explores walking's physical and psychological benefits. Also, with music from Herb Alpert, Mozart, Ella and Elvis. And she talks to Mark Hennessy, who's having to learn to walk all over again following a brain injury.
