It turned out that "running to the river carrying a boat on your head" triggered my then 18-year-old brother's undiagnosed heart condition.

The fact that he was otherwise fit as an ox and his friend knew how to do CPR, meant that after a multiple bypass op he was back riding a bike in a few weeks, and has since turned out fine as a patent lawyer ... oh wait ....

He had 3 caffeinated drinks. Obviously, he had a heart condition, but I'd guess this isn't the first time he'd had that much caffeine in his body. Kid just got dealt a shit hand.
