Nor is the problem limited to the . A 1992 United Nations Report labeled job stress “The 20th Century Disease” and a few years later the World Health Organization said it had become a “World Wide Epidemic.” A 1998 study reported that rapid changes in the workforce had resulted in a staggering unemployment rate of 10% in the European Union and higher rates of job stress complaints. Japan had a similar problem as a result of a major and prolonged recession. A subsequent European Commission survey found that:
•more than half of the 147 million workers in the European Union complained of having to work at a very high speed and under tight deadlines
•approximately half reported having monotonous or short, repetitive tasks and no opportunity to rotate tasks

The running ability of Tyrannosaurus rex has been intensively studied due to its relevance to interpretations of feeding behaviour and the biomechanics of scaling in giant predatory dinosaurs. Different studies using differing methodologies have produced a very wide range of top speed estimates and there is therefore a need to develop techniques that can improve these predictions. Here we present a new approach that combines two separate biomechanical techniques (multibody dynamic analysis and skeletal stress analysis) to demonstrate that true running gaits would probably lead to unacceptably high skeletal loads in T. rex . Combining these two approaches reduces the high-level of uncertainty in previous predictions associated with unknown soft tissue parameters in dinosaurs, and demonstrates that the relatively long limb segments of T. rex —long argued to indicate competent running ability—would actually have mechanically limited this species to walking gaits. Being limited to walking speeds contradicts arguments of high-speed pursuit predation for the largest bipedal dinosaurs like T. rex , and demonstrates the power of multiphysics approaches for locomotor reconstructions of extinct animals.
