A lot of people believe that death was invented in the early 1950s by the Coca Cola Corporation. Their researchers had discovered that older people were losing the taste for Coke and moving on to other carbonated beverages. The marketing people realized that unless something was done about it the older people would quickly out-number the younger coke drinkers. So they needed some way to redress the balance. Their first approach was to increase the number of young people by making sex more fun (see our wiki "Face to face with the missionary drawbacks"). This took off well until the effects were countered by the indtroduction (by Pepsi) of the Birth Control Pill.
