Some who are terminally ill want to be lab rats. You get one last shot at surviving and, perhaps more importantly, you also get to leave the world a little better by helping advance drug science. I don't think "lab rat" conveys the courage it takes to participate in a clinical trial and the gratitude we should have for them.
