Lets be honest about 'demonstrating rationality' here. If your goals are to have much more romping in the bedroom, they have done well here. However many of these techniques speak to me of cults, the ones with the leader getting all the brainwashed girls.

A much better sign of rationality is to have success in career, in money, in fame -- to be Successful. Not to just have more fun. Being successful hasn't been much demonstrated, though I am hopeful still.
