Reminds me of Spider Robinson's "Mind Killer". Could you imagine wiring yourself to provide "positive" feedback for any aspect of life? Want better grades? No problem - just give yourself a hit to the pleasure area - you'll be studying and make the grades. Of course, you may end up as a wirehead sitting in your own refuse and drooling. -Freeman > -----Original Message----- > From:[mailto:
