There's not only your soul you can sell. "Jonathon Keats, a 32-year-old conceptual artist and novelist, has announced plans to auction off futures contracts on 6 billion neurons in his brain, which he copyrighted this spring. The copyright, like all copyrights, lasts for the life of the creator plus 70 years." And the way of doing it was to copyright it as a sculpture which made it as an unique piece of art.
But Keats have also made Berkley to consider to pass the A=A-law: that everything in Berkley should be mandate to be equal to themselves. Keats, who is sort of a performance-actor in thinking, have really done a solid research to let the shareholders of his brain make a sustainable prediction of the financial value in buying his brain.
But the problem is that if the shareholders should get value from their investment Keats have to find a way to let his brain live after his bodily death. And he truly have the problem that he faces possible pressure not to endanger their investments. The days of hard partying could be over though "Thing is, though, if you get drunk enough, you can get lost and fall into the ocean and disappear, and then there is no brain. So the contract says you get a refund at full purchase price if the brain goes missing." (Wired News: He Thinks, Therefore He Sells)
