Logan's Run brought to life the idea that living 30 years was plenty. After that your little Lifeclock embedded on the palm of your hand would change color and you would go take your final ride of death on the Carousel.
Today designer Julijonas Urbonas has created something very similar, the "euthanasia coaster" and he describes it as an elegant and euphoric way to take the life of a human being. The very 'Humane' death coaster will drop you and spin you until your brain loses oxygen,"a legal indicator of death in many jurisdictions."
The ride lifts you half a kilometer to the top, there you can decide when to push the 'FALL button' and then its vision loss, confusion, and then your dead body will loop a few more times to ensure that this was indeed your final ride.
Urbonas speculates about the future use ofhis euthanasia machine and he thinks it can be used either for overpopulation, or "if your life becomes too long." Although its unclear whether he sees this "too long"scenario as a voluntary coaster ride or more of a mandatory one.
