Research presented at a conference suggested that jogging does work for longevity. Modest jogging from 1 to 2.5 hours per week divided into two or three sessions at a self-described slow to average pace was associated with a 44% reduction in the relative risk of death over 35 years compared with deaths among non-joggers, MedPage Today reported.The "runner's high" is anecdotally well-documented, so researchers tried to put a little data behind it. They compared dogs, notable long-distance runners, to ferrets, which are not, reported NPR. Dogs naturally produced cannabinoids, and the ferrets didn't.
Physicians in the story reported addiction-like responses among their patients, including those who mentally fall apart when injuries force them to rest instead of run.
