Red Bull overdose stops man's heart

Mathew Penbross felt like he needed a little boost while competing in a motocross event last weekend. The 28-year-old subsequently drank eight cans of Red Bull in five hours -- and it nearly killed him.

When ambulance crews arrived to deal with Penbross' overdose, they found that his heart had stopped, and he needed defibrillation. Fortunately the emergency medical technicians were able to save his life, but now the former energy drink-enthusiast is facing 6 weeks off work.

To be fair, the label on Red Bull cans clearly state that it's dangerous to consume more than 1.5 cans per day -- but what's alarming is that they've conveniently neglected to mention that going beyond their recommended limits could lead to sudden death.
