What happens when you drink eight Red Bull caffeine drinks:
Australian man, Matthew Penbross (28), found that out recently after drinking eight of the super-highly caffeinated beverages during a five hour period. I guess eight is his unlucky number, because after downing that last one he collapsed. An ambulance was called and the first aid crew found Penbross having a heart attack. Realizing his heart had stopped, they had to use a defibrillator to get his heart pumping again.
