Something to think about. The man who said running would extend your life, Jim Fixx, dropped dead at age 52. Running. My son and grandchildren are long distance runners and seem to be in perfect health.
But I am concerned with the strain on the heart over a period of time. I guess genes have a lot to do with it.
