Anxiety: My left hand is achy. Maybe I'm having a stroke.

Me: Your strength is fine and your typing is fine. I don't think a stroke would result in an aching hand.

Anxiety: I had this yesterday, too.

Me: Wait - haven't you been shoveling snow for the last two days? And you're right handed, so it's a lot of work your left hand is not used to.

Anxiety: Oh.
