Bacon has an ancient history. The domestication of pigs (immature hogs) for food dates back to about 7000 B.C. in the Middle East. Some historians say that bacon made from hogs was a favorite of the early Romans and Greeks. About 500 years ago, bacon or bacoun (a Middle English term) referred to all pork.
Although walking speeds can vary greatly depending on many factors such as height, weight, age, terrain, surface, load, culture, effort, and fitness, the average human walking speed is about 5.0 kilometres per hour (km/h), or about 3.1 miles per hour (mph).
Champion racewalkers can average more than 14 kilometres per hour (8.7 mph) over a distance of 20 kilometres (12 mi). An average human child achieves independent walking ability at around 11 months old.
