Years ago we came across a page called Deathforecast.com, which predicts how long you'll live depending on the answers to a couple dozen questions. That was morbid enough, but now there's something that does it one better by providing a constant physical reminder of one's mortality.
The "Life Index Watch" is a concept developed for a Timex competition that keeps track of your remaining days based on personal biometrics. And just to make sure you don't miss one nerve-wracking second, it's meant to be "worn like a patch on the skin," according to ProductDose.
Why anyone would want something like this is beyond us. Then again, maybe it's meant to remind us that life is short, so remember to enjoy thewhile we're here.
