If you genuinely want to improve your health, throw away the microwave.
Dont tell me you are one of those hippies from the 80's who got scared to not use a microwave because you didn't understand non-ionising radiation.
I know several old farts who have an aversion to microwaves like vampires do to garlic. Yet have no problem exposing themselves to the sun, dont use sunscreen or cover themselves up. Now they have to get Lazer treatments and skin grafts because melanoma is actual cancer from sun's radiation. I am told its a painful procedure.
Microwaves are harmless, just dont put your family jewels inside and you will be fine.
