How much of your favorite caffeinated drink would it take to kill you? Take this quick test and find out.
It would take 116 shots of espresso or 80 cups of drip coffee to kill me off. This is the lethal dose that kills 50% of the people given it (LD 50), so I'd have to imbibe this much coffee in direct succession.
Energy Fiend is also home to the Death by Penguin Mints calculator of death by chocolate.
