Ever wondered what would happen if you overdosed on Red Bull? Answer: your heart could stop ticking. I am not kidding.

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.

The obvious question: why was he drinking so much darn Red Bull?? Answer: he was competing in a motocross (motorcycle racing) event and wanted to get his adrenalin pumping. "It was to get a bit of a buzz and keep down my reaction time," says Penbross.

Penbross has gone public since his unfortunate RB-related incident. He says the product should sport a decent warning label. He says that current labels, which warn against consuming more than two cans per day, are inadequate. I guess a brush with death is more of a jolt than he was looking for...

Here's the thing: Penbross admits that prior to the heart attack he'd routinely drink four cans of Red Bull daily, which is twice the recommended maximum. Not only that: he also admits he continued to drink it even after experiencing chest pains. C'mon! I have no sympathy for the guy.
