Do You Mind?

In a world where the mind is fully understood and can be moved from body to body, people will grow spare bodies, but they need to be inhabited to keep from developing independent personalities. A career path will develop where someone (perhaps terminally ill and unable to afford a spare body) will hire themselves out to be implanted into a "baby" and "be" that person until it's time for the owner to inhabit it, at which time they do it all over again in a new one.
