There's a great joke by comedian Steven Wright that he knows when he's going to die because his birth certificate has an expiration date on it.

Funny, yes, but now it's one step closer to becoming a reality.

Deadline is a new app that claims it can predict when users will kick the bucket. It makes its guess based on a variety of factors, including blood pressure, height and sleep patterns.

(Side note: wouldn't it be an unbelievable horror movie idea if someone downloaded this only to see he's supposed to die tomorrow. You're welcome, now go write the script.)

It costs 99 cents, so, clearly, the cost shouldn't kill you.

Of course, this should all be taken with a grain of salt that you shouldn't eat, so you'll live longer:

Deadline uses statistical information to attempt to determine your date of expiration, but no app can really accurately determine when you will die, so consider this a way to motivate yourself to be healthier, and consult a physician as necessary."

So, now that you know when you're done, why don't you get off your duff and eat a big, fat pastrami sandwich and play some good old-fashioned Russian roulette while sharing lunch with the same silverware as someone suspected to have Ebola?
