"They can't see us," the girl explained. "One way glass."
"But do they, er, know why they are here?"
"Naturally. Everything's on the up-and-up with Bodies, Inc., morally if not legally."

"Your choice, Mr. Horner. As you can see, there are eight young men in there, each twenty-five years old, each guaranteed in good health, each perfectly willing to switch identities with you. I must tell you in advance, however, that the switch is quite permanent. There is no recourse. You understand?"
"Yes, but...." Horner looked at the eight men who could not see him, and lapsed into silence. The eight all looked like sound specimens, all right. All seemed healthy and alert, even cheerful. Horner said, somewhat suspiciously, "My reason for wanting to switch places is obvious. And theirs?"
It was a good body. It looked as though it would last for years.
