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.
This is the step-by-step process* of how mummification took place: 1  Insert a hook through a hole near the nose and pull out part of the brain. 2  Make a cut on the left side of the body near the tummy. 3  Remove all internal organs.  Let the internal organs 1  dry. Place the lungs, intestines, stomach and liver inside canopic jars.
