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.
Loss of cell phone reception inside of a building generally indicates that the following two issues may be present: 1. High electromagnetic interference (EMI) environment from dirty electricity that is being generated by electronic products. 2. Shielding and Faraday cage effects from metalwork in the building.
When listening to the lightning storms in your area on a standard AM radio, you will hear a sound like bacon frying and this is the electromagnetic energy that the storm is generating. Plants react to this energy and may show vigorous growth during lightning seasons.
