A Planet Called Utopia

A Planet Called Utopia is a science fiction novel by Scottish writer J. T. McIntosh, first published in August, 1979 in New York by Zebra Books.

Except for radio and television signals, which are tightly screened, it has been over sixty years since the last visitor was allowed into Utopia, a world where everyone was immortal.

So that the world's population would not outrun available surface area, marriage has been outlawed (because couples start to want to have a child), lifelong romances discouraged (for pretty much the same reason), and temporary personal relationships favored.

Life involves pleasure and adventure (skiing, scuba diving, parachuting, automobile racing) all day long.

But one step off the spaceship and onto the tarmac, he does the unthinkable, and the government is suddenly plunged into damage control mode before it's too late.
