Why would drinking increase exercise time? The authors don’t have a definitive answer. The survey results do not “follow expected patterns,” they admit, in which people who indulge in one unhealthy habit tend to indulge in others and vice versa. Smokers, for instance, statistically are less likely than average to exercise regularly and eat well. But this is not the case when it comes to drinking and exercise. Maybe, the authors speculate, some of the drinkers are drawn to a “sensation-taking lifestyle” that includes adventurous, extreme styles of exercise.
