Taking life too seriously? Maybe you should focus more on death. That’s the wisdom behind Tikker, a wristwatch that counts down the seconds you have left on this earth – and hopefully in the process motivates you to stop sweating the small stuff. Inventor Frederik Colting, a former gravedigger, created the portable grim reaper using an algorithm similar to that used by the U.S. government to calculate life expectancy. Watching your life slip away may be just the thing to help you to savor it more, but be careful: side effects of excessively morbid thinking include xenophobia among other things.
