The tikker watch was invented by Fredrik Colting and it counts down to your death. To set it up, you must fill out a questionnaire with information about your medical history, weight, lifestyle details such as if you drink or smoke and how often you exercise. When all of that and more is factored in, you are given a score representing your entire lifespan including the years you have already lived. After your current age is deducted from this score, the countdown begins. All of this of course, is just an approximation.
