Are we born to be physically lazy? A sophisticated if disconcerting new neurological study suggests that we probably are. It finds that even when we know that exercise is desirable and plan to work out, certain electrical signals within our brains may be nudging us toward being sedentary. The study’s authors (from universities including the University of British Columbia and the University of Geneva) hope, though, that learning how our minds may undermine our exercise intentions could give us renewed motivation to move. “Conserving energy was necessary” for us as a species in our early days, the study says. The fewer calories that atavistic humans burned, the fewer they had to replace at a time when food was not readily available. Bottom line: if you’re reluctant to exercise, you should maybe know that it is not just you, since we humans may have a natural bias toward inactivity. So, don’t feel bad if you often don’t feel too motivated.. it just might be genetics.
