When I signed up for life insurance, I was required to sign a form asserting that I have not "ever been instructed by a doctor to stop taking any prescription or non-prescription medication".

Uh, what? Apparently, what's meant is a doctor never told you to stop abuse of a drug. But that's not what it said, and I ended up having to go the 'subversive' route and submit the forms on paper, with this line crossed out, and an explanation attached.
