a couple of years ago, the mad scientists in me thought about a business where we preserve the brains of people a la Futurama. When the body dies, the brain does not necessarily have to follow. Possible? Yes. Feed it the right chemical cocktail, O2, remove waste products. Ethical/Moral? Whose to say? We are preserving life..in a sense. Profitable - Sure. Connect it to a keyboard/mouse interface. I mean we already have business cyro-preserving with the hope of unfreezing in the distant future!
