"Dr. Bennet asked me to come back today," the little man said. "Follow-up on last week's work."

"Name please?" The woman took his name and punched the button on a panel before her; an instant later a card flipped down in a slot. She checked it, made an entry and nodded to the man. "Dr. Bennet will be ready for you at eleven. You'll find magazines in the lounge." She indicated another door, and the little man disappeared through it.

Or you could give blood, but the law restricts you to once every three months on that, and it only pays thirty-five dollars. Or—"

The woman's eyes narrowed. "There are higher-paying categories of Volunteer work, of course. But you must understand that they are higher paying because they involve a greater risk to the health of the Volunteer. For instance, we've been running circulation studies with heart catheterizations. We pay a hundred dollars for these, but there is an appreciable risk involved. Or sternal marrow punctures for blood studies. Usually we start—"
