A team led by Vincent Careau, a PhD student at University of Sherbrooke, gathered data on many aspects of dog biology published in disparate fields of study such as psychology, longevity, and veterinary research. The information was well known in the respective research domains, yet they were never put together. By doing so, the authors show that obedient breeds - on average - live longer than disobedient breeds. They also show that aggressive breeds have higher energy expenditure. The late Don Thomas said, "It is hard to imagine how an aggressive personality could be adaptive if it lacked the energetic and metabolic machinery to back up the threats. Simply put, 100 pound weaklings don't kick sand in weight-lifters' faces and survive in nature."
Do calm people live longer than high energy people? Anyone know of studies that compare personality traits and longevity?
