No cars, no medicine, no
microwaves, no phones—just unplug from everything science has given you and leave the rest of us alone. Microwaves vary from model to model, and can range from about 300 watts to 1000 watts or more.
People blindly following instructions may not realize they have
microwaves with a wattage lower than the instructions specify.
New studies suggest that prenatal exposure to anti-depressants,
microwaves and cellphones may lead to ADHD and autism. Historical Examples of microwaves

An electromagnetic wave with a frequency in the range of 100 megahertz to 30 gigahertz (lower than infrared but higher than other radio waves). Microwaves are used in radar, radio transmission, cooking, and other applications. Microwaves are generated naturally by many astronomical phenomena and are found in cosmic background radiation.

Electromagnetic waves with a wavelength on the order of a few inches. Microwaves are longer than infrared radiation and shorter than radio waves. Microwaves are used extensively for communication, both in satellite television and for the transmission of long-distance telephone signals. In a microwave oven, food is cooked by the heat generated when the water in the food absorbs microwaves.
