re: "the one that actually holds up is a higher incidence of cataracts in people who have had significant exposure to microwave energy (aka radar techs): Heat from a heating pad will do it, so, I imagine, adequate heating energy from a uwave will too. I have had personal experience with this. I am stating this as fact. The blinding event, one eye only, took place 20 years back. Fixed now, lens only was affected.
