The top easily preventable health problems that I see in western societies are: 1. Eating chemically grown food. 2. Exposure to electronically generated harmonic energy from wind and solar power systems. 3. Exposure to harmonic energy from switched mode power supplies (SMPS) that come with modern electronic products. 4. Exposure to wireless radio frequency radiation (RF). 5. Light deficiency from an indoor lifestyle and Low-E double glazed windows. 6. Sound deficiency from heavily insulated homes that are devoid of natural sounds and are extremely quiet. 7. Pollen deficiency from living in man-made cities that are devoid of natural levels of pollen. 8. Natural radiation deficiency from living in homes that block natural levels of environmental radiation. 9. Open drain sickness that occurs when drain traps dry out and faulty vent valves that allow sewer gas to fill the home. 10. Drinking the wrong type of water.
