aka BS
How many believe every bit of BS they hear and still have functioning lives? LOL
The power of belief is not to be underestimated though, it is well known and well documented and hence why things like double blind studies were devised to account for the placebo effect. However in this case there should be a control group tested where they are told that their PB bands are not genuine and compared with a second group who are told that they have genuine PB bands. The sneaky bit is that the genuine and non genuine PB bands are mixed up randomly (so that even the testers don't know what is what).
It would be a bit like telling one group of riders they are riding Giants and the other group that they are riding Specialized, or Pinarello riders that their bike is made in Italy LOL What I'm getting at is what is the difference between genuine and non-genuine?
