Yes, there is a proven placebo effect.<quoted text>I believe that there is power "in" belief.
Unless you believe there can be no faith, and vice verse. Belief can produce real results in the real world. Deny it all you want.
It can also be a source of comfort during difficult times--a crutch, if you will.
Some of us though, those who are critical thinkers and cannot accept anything without evidence, are unable to suspend our disbelief to take advantage of these benefits.
