With 70 percent of the population dying so young burial was essential and the first methods of burial were simple sand pits. The body was layered within the sand pit, provided with offering pots of bread and beer plus any personal items, a reed mat was then placed over the body and the sand was filled in. The hot sand, which came into contact with the body, produced natural mummification. The drawback with this method of burial was the wind in the dessert area would blow the sand out of the grave exposing the body to scavengers, which lived in the dessert areas. The Egyptians came up with producing large pots and stuffed the body within the pots and then placed the pots into the sand pit. Unfortunately this was an expensive method of burial, which only the very rich could afford. So the Egyptians again dug sand pits but this time lined the inside walls with stone, placed the body within the chamber, and then sealed the open pit with a mud brick wall, this was an extremely cheap method of burial and kept out the scavengers, the drawback was the loss of contact of the hot sand against the body which led to the body decomposing, so the Egyptians developed the method of mummification.
Seventy percent of Egyptians came into contact with the land and the Nile. One of the biggest unseen problems in ancient times was the Nile worm. The worm would enter the body and work its way slowly under the skin until it reached the kidneys. Once there, it would lay eggs starting a new generation of worms. Because of this affliction many ancient Egyptians died at between 30 35 years of age. The Richer people in society, who did not have contact with the land suffered with malaria, fevers and other pester lance, these people within the higher ranks of society would only live to 50 60 years of age.
