Here is a case where knowing the truth is a disadvantage. If I think a sugar pill is real medicine, I get better. If I know it's just a sugar pill, I don't. If one day I learn that Compound x from the health food store which I have been taking for years and found to be useful is really physically ineffective and works as a placebo, I lose a psychological advantage. How then do I mobilize my mind's resources to accomplish what Compound x used to help me do? Phil Tompkins Hoboken NJ age 60/dx 1990
