in the '70s, hypnosis and meditation etc. were all very much in vogue. my father had already just barely flunked the bar exam twice. he was not a test-taker at all, would get very very nervous.
he went to a popular hypnotist who was using a new rhyming method. the line was, "if you can drive a car, you can pass the bar."
my father flunked the bar the third time and from then on would start violently shaking whenever he tried to drive on the freeway. he was okay on streets, but couldn't drive on a freeway. all of my childhood he drove on streets only, and any family vacation had to be by airplane.
i wish i were joking about this.
also, i like my brain. i wouldn't trust anyone or anything (no drugs) with it, so why pay a total stranger (even if he's highly recommended) to go fiddling around up there?
