What do dead bodies smell of?

Dead bodies typically emit a strong, unpleasant odor due to the decomposition process. This smell is primarily caused by the breakdown of tissues and the activity of bacteria, which produce gases such as hydrogen sulfide and ammonia. The scent can be described as a combination of decay, rot, and often a sweetish undertone due to the release of fatty acids. Environmental factors, such as temperature and humidity, can also influence the intensity of the odor.
