P E T S avoid unnecessary muscular exertion. A cheetah running at 120 km per hour in short bursts with every muscle in action is energetically understandable because losing the dinner would be a far more serious matter than expending some energy. That is why cheetahs usually just walk to maintain efficient low energy expenditure. Slow metabolism We, humans and our primate cousins, however, possess a great secret advantage. We hold a far slower metabolism. During an average day, we expend 50% less energy than other mammals of equivalent weight. To date, scientists cannot explain this huge physiological energetic gap. Humans would need to run a marathon every day to be on the same level of energy expenditure with non-primates mammals, like cheetahs. Nobody knows how and why primates came to expend so little energy.
