I don't know what's scummier, Del. As it stands right now, you're the only one who doesn't want to go through with the test. You seemed to be for it earlier today, why the sudden change of heart?

I'm going to keep my vote, I want to see more opinions on that, especially going to be looking for the opinion of the possibly actual doctor.
