In Response to Skeptics

Alot of Polyphasic sleep cycle skeptics hint at or say (wikipedia.org) that the reason that the schedule works is becuase it is all in their head...users want it to work so bad that their wishful thinking gets them through it and/or that adrenaline is being released that is causing them to be alert on so little sleep.

I guess my response to this is, so what? I mean why not use the power of positive thinking? and if in some wierd way the sleep cycle causes a release in adrenaline then why don't we harness that, embrace that and add it as an advantage?
