I had a friend, Edgar Willis who was a chiropractor (I was NOT a dub then) who practiced that method on some patients, including Bill Walton (that really tall, ugly basketball guy) . I was pretty young and fairly vigorous and had a digital watch on my right hand. I'm left-handed. He asked me to hold both my arms out at shoulder-length, so I did. He then said he would reach out near both my hands and try to pull my arms down with all his strength, which he did. He pulled them both down, but I distinctly noticed that my non-watch (left) arm gave him MUCH more resistence than my watch-arm.
He then asked me to put my battery-powered watch on my left wrist. I did. We did the same exercise again, and I swear on my heart-of-hearts that my left arm now became the weak arm. It was so noticeable and I won't forget it. I asked him why this interesting phenom. happened and he said that our bodies are electrical, and that even the weak power of batteries in watches affect us.
Wow! He said that energies flow from one side of our bodies to the other and that batteries can affect that, too.
I tossed my watch and haven't worn a battery-powered watch since. I don't know much about anything, but I know that demonstration told me that if I'm ever to be any super-hulk type of guy, I need to use sundials for my time-keeping.
The only lie in this story is that I do not use sundials for my time-keeping these days. All the rest of this story is probably true.
