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.
In order to reach the afterlife, Egyptians had to lead a good life and preserve the body. The Egyptians believed that every individual had a ka. It was a spiritual twin of an individual, like a soul. The ka would live forever in the afterlife. The body had to be preserved so that the ka could live in the afterlife. There were several steps involved in mummification. The ultimate aim was to completely dry the body to stop decomposition while maintaining a life-like appearance. After the individual had died, he or she was taken to a special embalming area. The body was first washed in an antiseptic salt solution. The internal organs were removed and dried.
