Lack of Exercise Is a Global Concern
Americans aren't the only ones slowing down—or, more accurately, sitting still. A series of studies found that people across the globe are becoming more sedentary and that the lack of exercise is as serious a killer as smoking. Researchers found that 31 percent of adults worldwide are sedentary and that 80 percent of adolescents get less than an hour of exercise per day. People from richer nations, such as the United States and Sweden, were more likely to be inactive than those from poorer countries. Another study found that 5.3 million people worldwide die each year from diseases linked to inactive lifestyles, more even than the 5 million deaths a year caused by smoking.
