8 years ago I attended a Tony Robbins Seminar in Hawaii. I never forgot those days. Tony recorded a video, which he put on the net now in honor to 9-11. I learned a lot at that time and I really recommend to have a look at it. Watch it and make your own decision.http://tonyrobbinscoachtraining.com/
In 1997 I accompanied my former boyfriend going apnoe-diving (Koh Tao, Thailand). I was his scuba-diving back-up at 40m. I remember the strange feeling, as he passed me, with ordinary mask, scuba-fins and load only and disappeared into the blue depth. No reference-rope. On his way back he was a bit disoriented, but finally made it. Without yoga...
