I can remeber back in the late 70s, I think it was, when I had my first microwave oven and had zo check it every now and again with a little meter to see if it was leaking
I also recall not that many years ago, a work colleague said that she "would never have a microwave oven in her kitchen beacuse she
does not warm up leftovers!"

. I tried to point out to her that you can cook a complete and very healthy meal in a microwave (much to no avail).
