In Perfect Motion, Jono Lineen investigates that transformation, and why walking has made us more creative, helped us to learn, constructed our perception of time, strengthened our resilience and provided a way of making sense of our life - and death.After the tragic loss of his younger brother, Lineen experienced walking’s regenerative power firsthand. Grief-stricken and adrift, he set off on a 2700-kilometre solo trek across the Himalayas. He walked for months until his legs ached and feet blistered, and by the end of the expedition something had changed in him. He was stronger - not just physically, but psychologically and emotionally.What had happened? What had given him this feeling of peace; joy even? Determined to find out, he began researching the science and history of walking and running, and discovered that there were fascinating reasons for his metamorphosis. Now, weaving together his own remarkable personal stories with evolutionary research, psychology, neuroscience, anatomy and philosophy, Lineen reveals for the first time the powerful effect that even the shortest strolls can have on us. And why walking is what we’re made to do; it is our perfect motion.
