Maggots, which are actually the larvae of flies, have helped doctors clean wounds on and off the battlefield since Napoleon's time. Around 12 hours after death, the body will feel cool, and within 24 hours (depending on body fat and external temperatures), it will lose all internal heat in a process called algor mortis.
