That’s what the Copenhagen City Heart Study would tell you! And that’s no small fad study, either! It’s been ongoing since 1976, with the first set of data collected between 1976 and 1978, the second from 1981 to 1983, the third from 1991 to 1994, and the fourth from 2001 to 2003. The study followed 20,000 men and women of all different ages, between 20 and 90. Among them were 1,116 male joggers and 762 female joggers. Further, this study has been cited in over 750 scientific papers!
