We are all going to die someday. You know that, right? But do we need to be reminded of it daily? Or better yet, do we need to know just about when it will happen, based on how we’re taking care of ourselves? The makers of Tikker, or “death watch,” think so. It lets its wearers know how much time they have left here on Earth, right down to the second. Invented by Fredrik Colting, who prefers to call it the “Happiness Watch,” the counting mechanism translates a survey of medical history and habits into a supposed accurate prediction of when you’ll die. Something tells me this is yet another watch that won’t get a battery replacement once its day arrives.
