"I've discovered that going for a daily walk has become as essential to me feeling good for the rest of the day as that first cup of tea. But I would argue that all I am doing is responding to a natural need we all have. Humans have always been migrants, the physiological urge to be nomadic is deep-rooted in all of us and perhaps because of that our brains are stimulated by walking. I solve all sorts of problems, formulate ideas, work things out to that gentle rhythm of self-propelled movement." Thinking on My Feet tells the story of Kate's walking year - shining a light on the benefits of this simple activity. As she explores the reasons why we walk, whether for creative energy, challenge and pleasure, or therapeutic benefits, Kate's reflections and insights will encourage, motivate and spur readers into action.
