Walking

From Encyc

Walking is a form of transportation involving rhythmic movements of weight-bearing appendages.

It can also be form of exercise, coupled with a strict diet, which will help improve physical fitness.

Devices that have freed people from the necessity of walking include the automobile, elevator, remote control, and cordless telephone.

Most animals walk on four or more legs. Humans are rather unique in their bipedal (two-legged) walking style.
