The runners i run with, run for the love of it. Not to, lose weight, fit in a outfit, or have a nice body. Those are just a bonuses. It's more than that!
Random thought, while getting ready for work. I wonder how many people would be married, if marriage was like a military contract. Married for a few years, then move on to the next, or either extend your marriage, if you want to stay with them longer.
