That's right, you can donate your body to forensic science to get around having to do any of that traditional funeral crap or encouraging the use of noxious chemical preservation. The Forensic Anthropology Center at the University of Tennessee will let you rot (in a shallow grave, in the trunk of a car, at the bottom of a pond, etc.) naturally and chemical-free, and measure the stages of decomposition. This furthers forensic science and helps put murderers behind bars.
If forensics really turns you on, you need to add these fascinating, factual, and disgusting volumes to your library:
Death's Acre by Dr. Bill Bass (the Farm's founder) and Jon Jefferson
