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).
A 160-lb. person who walks only 35 minutes daily for 15 years weighs 18 fewer lbs. than a nonwalker, according to Harvard Men's Health Watch. Distance walking can help you lose more weight in less time. Walking 4 mph for an hour burns 334 calories, or slightly less than one-tenth of a pound if you weigh 155 lbs. Consequently, you can lose almost 18 lbs. in one year if you walked 4 miles almost every other day, or 180 times, during a year.
