Brad Hampson, a 41-year-old pharmacist who lives in Chicago, is not the kind of sports fan who loses his temper when his team gets beaten. But the outcome of a game definitely can affect his mood.
Watching the Nationals beat the Cubs on opening day at Wrigley Field was "heartbreaking" for Hampson, a lifelong Cubs fan.
"I'm upset when they lose and happy when they win," said Hampson, who has traveled to almost every current major ballpark in the United States. Hampson loves all sports, but says baseball is his favorite.
"It's a pleasant diversion -- at least when they are winning."
Researchers have long been interested in studying the characteristics, habits and overall health of sports fans. They've studied alcohol consumption, testosterone levels, even cardiac arrest rates after a Super Bowl game.
