We already told you how exercise makes you fat. Now we learn that people who drink more also exercise more. So if A=B and B=C, does that mean heavy drinkers are fatter than non-drinkers because they exercise more? Or because they imbibe a half dozen 200-calorie drinks a night?

Reuters: "People who drink regularly seem to exercise more often than teetotalers, and those who average more than a drink or two a day may be the most active, a new study suggests. Using data from a government health survey of U.S. adults, researchers found that in general, the amount of time people devoted to exercise tended to inch up along with the number of alcoholic drinks they had each month. Compared with abstainers, those considered heavy drinkers — at least 46 drinks in the past month for women, and 76 or more for men — exercised for an average of 20 minutes more per week."

Of course, we might be dealing with some idiot logic here. Just because heavy drinkers tend to exercise more doesn't necessarily mean they're healthier. Also, they may be exercising just to keep off that beer gut, and thus exercise is a necessity to counter excess calories. Either way, if you've found a way to party hard and stay trim, more power to ya.
