Immortality, Inc. by Robert Sheckley
Paperback – Bantam – 1959
“Want to be immortal? You can in 2110 A.D. Just go to the Hereafter Insurance Corporation and hook yourself up to The Machine. There’s nothing to fear. That is…if it happens to be working right, and if nobody slips another mind into your body while you’re not looking, and if you’re not on a poltergeist hate-list….
Immortality, Inc. is the trenchantly witty novel of a future where everything has improved except the bumbling human race, which just plain can’t let itself enjoy a good thing when it finally gets it.”
