There are legit health reasons to opt out of the scanner. I know because I have one of those conditions and have never been through the scanner.

That's fine, but you don't need a health condition, legit or otherwise, to opt out. It's enough to say "I would like to opt out."

Millimeter wave scanners have a health exemption? Like because it would always detect something on your body?

What is an example of such a condition?

Pacemaker, pregnancy, probably others.

Mass hysteria.
