When we were growing up, when someone said physical activity they usually meant exercise, or exercise and physical activity were one and the same. That was also a time when we walked or rode our bikes everywhere, at school we had daily physical education and recess three times per day, and playing outside with neighborhood friends was the best social opportunity a kid could have. We didn't have computers or cell phones, our families had only one car, and while we had television, we only had a handful of channels. Television programs were geared mostly to adult viewers and signed off in the late evening. We had cartoons, but they were only on Saturday morning until 10:00 a.m.
