Tip of the Day!

This morning when I arrived at work I found this article in my box. With a tip of the day. Highlighted was dog walkers lost an average of 14.5 pounds but they end of a yearlong study. I am pondering who and why someone put this in my box. For one thing I have lost 15 pounds over the last 6 months by just eating less and now weight 140 pounds. So being 5'8" that is not too bad. Now, wonder, WHO and WHY!
