Which factor does NOT typically affect the decomposition of a body?

Human emotions do not have a measurable impact on the physical processes involved in decomposition. Decomposition is primarily driven by biological and environmental factors, such as the presence of bacteria, the composition of the soil, weather conditions, and insect activity, which all facilitate the breakdown of organic matter.

Soil composition plays a significant role because different types of soil can influence moisture retention and drainage, affecting microbial activity and the rate of decay. Weather conditions, including temperature and humidity, are critical as they can accelerate or slow down the decomposition process. Insect activity, particularly from scavengers like beetles and maggots, helps to break down tissues and accelerate decomposition by feeding on the remains.

Therefore, while emotions can influence human behavior and interactions with the deceased, they do not alter the biological processes that lead to decomposition.
