If you are refusing to give it a decent try, and let go of your concrete mindset, just because there is "nothing that can prove it works," then please either disprove it, and do more than just talking about it here. If you can prove that it doesn't work, then be my guest!
If it's evidence and proof you want, no amount of anyone else's submissions will be enough for you. You have to either prove it, or disprove it for yourself.
