People who are less likely to exercise and not attracted towards athletic activities are more docile leading to suggestion of a link between an individual's capacity to generate energy and his personality.
Researchers from the University of New South Wales, Australia, studied the behavior of various animals and found that those who are couch potatoes are more docile compared to those who actively participate in athletic sports.
The researchers went on to add that the rate of metabolism also defined the personality of an individual. People with high rate of metabolism tended to be more aggressive and dominating compared to those who had low rate of metabolism.
"Some of us are couch potatoes while others are drawn to sport and exercise. We often associate the athletic 'jock' type or person with being aggressive and social, whereas the more sedentary 'nerd' often is seen as more socially awkward and submissive", lead researcher Peter Biro said.
