This is kind of in support to my welcome post.
There is an article in the New England Journal of Medicine linking heart failure to die hard sports fans.
The study was done during the 2006 World Cup in Germany on Germans watching the games. They found that on days the German team played, cardiac emergencies more than tripled for men and nearly doubled for women. How the team played, the overall importance of the match and whether the winner was determined by a shootout all affected fans’ heart risks.
The risk was highest for fans who already had heart disease. Their chance of having a heart attack or other cardiac events during the tournament was four times higher, while risk doubled for those who didn’t have a prior history of heart problems.
Of course the study made no mention of the fact many of these German fans were probably regular drinkers and probably mixed in the occasional hot wing, nacho, cheese fries or whatever the hell they eat.
That stuff couldn't have helped either.
