The world needs exercise pills, which are not in market yet. Some of the most costly public health menaces in the United States, for instance, stem from our sedentary lifestyles, including obesity, diabetes and heart disease.
In theory, good old’ fashioned exercise would help far more than any pill—but only if people actually did it.
Studies suggest that 62 percent of heart disease survivors stick to a workout regimen one year after nearly dying from lack of exercise.
Other studies have found that, while 80 percent of heart disease patients know they should exercise, less than 40 percent maintain any sort of workout regimen.
Some patients say they can’t exercise because of their diseases. Others say they simply don’t have the time.
