Ever just sit in a park and smell the scents. Then watch the people. Each person has their own purpose of being there. Parents with children. Teens doing teen things. Dog walking their owners. Workers mowing, weeding, etc. And then there is the exercise group. With their fitbits or vivofit or other devices to tell them they are exercising. Because in this age everything has to be measured. The sweat and tired muscles no longer seem quite .... enough.
