Friends Come in Boxes

The problem of immortality had been solved in the 21st century: when you reached forty, your brain was transferred to the head of a six-month-old infant. In that way, you obtained another forty years of life, until you could do it all over again. But nobody could have foreseen the dramatic manner in which the birthrate would fall - resulting in a growing waiting list for host bodies, and the creation of Friendship Boxes to house the brains of those who waited. The Friendship Boxes proliferated: a grumbling section of the community, a constant source of embarrassment to every politician... Until the day it all came to a head.
