Jogging in the 50-60s was what's meditation today: it was gaining popularity, but if you told someone you'll go for a run, they looked at your weird, asking "who's chasing you?"
This is something my mom told me before, and so I'm not quite sure how true it really is. But, if it was true, I'm sure there were a few articles out there titled "Can We End the Jogging Madness?"
