I've been running regularly since age 20, almost 40 years, and have never had a problem or injuries. I recommend jogging pleasurably, not running against time or competing with others informally or in marathons, and changing shoes every 4-6 months as the bounce begins to wear out. Make it fun and I think your body will take care of the rest. Pain is not necessarily gain.
