Dr James’ research found that tourists are those most likely to cause IED. They are the slowest walkers, at an average of 1.16 metres per second. IED sufferers should easily be able to spot tourists and change course to avoid any chances of getting angry. Next slowest are smokers, cellphone users, and people with bags. These walk between 1.27 and 1.3 metres per second. The fastest walkers, at 1.4 metres per second, are those who listen to music. New York resident Jim Redman said he was shocked when he found out about the research. “That’s me!” he said. “I get sidewalk rage every day. I can’t stand it when people walk so slow in the city. I have no patience with them,” he added. Mr Redman confessed that he also showed signs of IED in his home when his children slow down his journey to the bathroom.
