I stopped going into public pools or hot tubs decades ago. Parasites are contaminating public pools and chlorine does not kill them. Today’s world is even more risky, for many reasons. One of which is that are immune systems and gut microbe have been damaged by a myriad of poisons. The worst offenders are gylcophate, heavey metals and EMF ( Smart Meters, Cell towers/Phones and Wi-Fi. Today more than ever, prevention protocols are imperative!
