For the record, 'blood work' is a common term for having blood drawn for the purpose of tests and evaluations.
Anyway, I can't have blood drawn. I literally faint. It's weird too because I faint after the blood is finished being drawn, it's kind of like a cruel way my body makes the entire experience as terrible as possible for me. I get to experience all the unpleasant lightheadedness, dizziness, and nausea during the extraction, then as icing on the cake after they finish, pat me on the shoulder, and say 'You're done,' I get the grand prize of straight passing out. Then they don't let me leave for an hour because I'm a safety risk to drive myself home after just passing out. Fun stuff.
