As most of us would likely guess, walking is the most popular physical activity in America. But people who walk for exercise do so at wildly varying speeds and intensities. Some stroll at a leisurely 2 miles per hour, which is low-intensity exercise. Others zip along at twice that pace or better, resulting in a sweatier workout.
Mummification is a process in which the skin and flesh of a corpse can be preserved. The process can occur either naturally, or it can be intentional. If it occurs naturally, it is the result of cold (as can be found in a glacier), acid (as can be found in a bog) or dryness.
How Mummies Were Made. First the body was cleaned with a wine solution and spices. This was to kill as many bacteria as possible and stop the body from decaying. Then all the organs that could decay were removed.
