My career began somewhat accidentally. In the 1960s, I started a practice in the fledgling field of mind-body healing. Around that time, it was completely in its infancy. I had been developing a protocol to use body awareness as a tool for stress reduction.

Now, what happens whenever there's a loud sound is that it startles us, right? And we arrest what we're doing, and we try to localize that sound because that sound could be a threat. That's something that's hard-wired in our bodies.

Basically, in the fight-or-flight response, the objective is to get away from the source of threat. All of our muscles prepare for this escape by increasing their tension level, our heart rate and respiration increase, and our whole basic metabolic system is flooded with adrenaline.
