Think coffee helps you stay productive through the day while you bang away at your keyboard? Ok, so it does. But how would you feel if you knew the exact amounts of coffee or caffeine it would take in order to stop your heart?

The online "death by caffeine" tool calculates your weight with your beverage of choice and serves up some stats on how many cups it will take in order for you to drop dead.

They have also put together a caffeine database chart that compares how many MG's of caffeine are in a drink. Ok, enough writing, its time for my 4th cup of Starbucks. 30.86 more to go.
