4. Religious Self-Mummification
Here’s an interesting fact about the Sokushinbutsu Buddhist monks of Japan. To self-mummify, they committed suicide by living on a seed and nut diet for a thousand days, poisonous tea to make their flesh unpalatable to the ubiquitous maggot for another thousand days before retiring to a tomb for the eternal slumber. What a nice way of sending your local embalmer to inflation!
