Scientists in Denmark have been studying over 1，000 joggers and nonjoggers for 12 years.The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die.The best speed to jog at was found to be about 5 miles per hour.The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as nonjoggers.The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉)Over time, this can cause serious injuries.Peter Schnohr, a re
