Fewer Americans are obeying speed limits, exercising vigorously or paying close attention to the fiber and sodium in their diets. And adding to the list of unhealthy behavior, they're eating less broccoli.
Almost two-thirds feel stressed out at least once a week, and three in 10 get by on six hours of sleep a night or less. All told, the average American practices only two-thirds of the behaviors that signal a healthy lifestyle, an annual ranking produced by the health magazine Prevention shows.
