Walking, for someone like Khusbir Kaur, the national record holder in the 20-kilometre race walk event, is serious business. The rest of us generally do not give it much thought. It’s part of our daily life, but have you ever wondered why we walk the way we walk? How do our bodies ensure that we walk in the most energy-efficient manner? And, biomechanics aside, when and why did we switch to moving about on two limbs? The answers, The Intersection finds out, are fascinating, and can lead to a better understanding of the human walk, which can have major practical applications.
