I have seen some hobby descriptions get really pedantic, which can be somewhat amusing.
Experience (hobby): Walking - 80,000 hours
Description: Walking is the most common form of human locomotion, primarily involving the bones, muscles, and soft tissues of the lower extremities and pelvic girdle. I began walking at 12 months of age, and since then have really learned to value my ability to get from point A to point B without mechanical assistance. I have walked around houses, across lawns and parks, down sidewalks, and through commercial buildings. Each walk permits the opportunity to engage all of the senses and learn new things. You never know what will happen when you take a walk!
