Running makes you live longer?

I read somewhere that for every mile you jog, you add a minute onto your life. I don't see how this can be true... is it?

Same thing as eating fish three times a week extending your life, or regularly eating fruits & vegetables. It's all statistics. That doesn't mean you will necessarily live longer, but that the odds are better that you'll live longer. Also, if you exercise & eat better, you'll be more likely to enjoy your life, if you live longer or not.
