Now I wouldn't go so far as to call it "brainwashing" but it was definitely an enlightening experience for me. I went through the 7-day program. The food was excellent and the facilities were extremely clean. In fact, our sleeping quarters were completely white. From the walls to the floors to the sheets on the bed, everything was completely pure white with a trim of "glow-in-the-dark" blue to show us where the doorways were. It felt like being on a spaceship.
My only disappointment was that they didn't give us a lot of swag to take home with us. All I got was a small bag containing a leatherette iPhone 6 case, some Apple logo stickers, and this T-shirt.
I wish I could speak about the seminars I attended but I'm afraid I'm sworn to secrecy. I am one of them now.

Well, now ... you’re just making me jealous, with your cool t-shirt!
Cool beans!
