This particular podcast deals with the poorly-understood placebo effect. It is not just sugar pills, it highlights the power of the mind and the natural responses it triggers in the body. He interviews Dr. Kathryn Hall who is the director of placebo studies at Harvard University
The short version of it basically states that certain stimuli, even when told are essentially nothing more than a placebo, it still produces physiological responces that are based on the expectancy of something to happen. Sound familiar?
