Interesting, I’ll talk with my doc. He just Okayed biofeedback to get my heart back in rhythm before ghastly “cardioversion” procedure, one possible side effect is death. NO WAY JOSE.
Actually, I was a biofeedback genius, was featured on some big national TV show long ago changing. my brain waves. Can also change heart rhythm, virtually anything else. Been a very long time, but I just ordered a biofeedback tester from AMZ, will see how well I can do now.
