Increasingly it seems, we are learning the human body is a more marvelously complex entity than we imagined. We are also learning that with as much as we know, there is still far more to learn. This study no doubt explains why despite years of physical education in schools, individuals “self regulate” their physical activities in quite unique ways. Thus, is is likely that just as with so many genetically determined factors, levels of activity may well be genetically “pre-programmed” into us. Changing that programming is likely not possible, though conscious efforts to alter behavior can also likely overcome the body’s pre-set preferences. With a national epidemic of obesity, this study should not be used as an excuse to explain why we cannot exercise or be more active. Being sedentary may be natural for many, but in adult life it becomes a choice, regardless of genetics . . . ben kazie md
