Family involvement is a valuable thing and playing together actively can be the '90s version of it. Instead of just watching you can do it together... something we don't spend enough time on. We can motivate and excite each other about fitness.
My dad was a Marine. He was one of the Montford Point Marines. Those are the equivalent of the Tuskegee Airmen for Marines. He's a tough tough guy. When I was 15 we had a fight and I didn't speak to him for 10 years.
