My walking routine--no rain today

No one has ever accused me of being an athlete, but I do walk 2 miles every morning along the lake front and maybe another 2-3 miles during the day. Or maybe it's a stroll. However, this morning on my walk I fell in step with a younger woman, about 65 maybe, and she was really stepping. I changed my pace because we live on the same street and it seemed rude to fall down on a park bench to catch my breath. I barely made it to my front porch before I collapsed.
