The Tikker watch counts down to the second how much time you have left to live. - 

This final note today. You're gonna think I'm making this up, but I'm not: A 'death watch' counting down to the time you die.

It's a Kickstarter campaign -- they ask you a bunch of lifestyle questions and figure out how much time you have left -- years, months, days, hours, minutes, seconds. They're looking for $25,000.
