Does the magnet around my neck affect my brain pattern. OK, I've not got a very big brain, but it's far more powerful than the most powerful computer ever invented by humans. But does the magnet do things to me? It sure gets on my tits, I know that much. How would YOU like to walk about with er, well I weigh 2000gms divided by 15 gms (the ball) er, times by 100 % = .0075% ....take average overweight human at 80000gms....er thats .0075% = about 600gms....dangling from your neck eh?
