The Undertakers in America run quite a sick, vicious racket. They are protected by the government to gouge you and your family during a grief-ridden time. Case in point, I would prefer to be cremated instead of wasting useful resources (land, metal and chemicals) because the resurrection claim most Christians buy into happens to be the premise to contemporary zombie movies. However, the funeral parlors can still stick you for thousands on this option, thus destroying any savings you could leave your heirs. According to the Carl Hiassen novel Sick Puppy, Florida law requires the purchase of a casket despite cremation.
The scientist in this link has an even better, more productive option! I definitely would opt for the expensive strains she used, shittake. Maybe they could offset how expensive my wake may be, or what I call the “I’m Glad Steve is Dead Party!” I know there has to be some wealthy Japanese businessmen who want mushrooms with a hint of Starbucks, Whataburger and Coke Zero. You can’t get those exotic flavors in Soylent Green!
