"Hey Grandpa, do you remember all those Jane Fonda dance tapes with the crazy neon colored tights and leg warmers?"
"Well, son, yes I do. Those were wild times. But that was in the 80s. None that existed back in the 70s.
"So people didn't exercise in the 70s?"
"Well they did, but the fashions were taken more from traditional dance. For example."
"Well son, you could still have fun."
"Okay, smart alack. You want to see some serious dance faces?"
"Okay, okay, you want dancing. Here's some dancing."
"I guess that counts as dancing. However, I don't see mom doing moves like that when she's working out to her Beach Body Workout tape."
"Well son, this was a long, LONG time before workouts like that."
"Back in the 70s, we didn't have Beach Body, Brazilian Butt Lift, Insanity, or P90x streaming into our home TV. No, instead we had the Sears Exercise Shop!! Yes, in many ways times were simpler back then"
"Grandpa, I noticed all these gals covered their legs. Why?"
"But these gals don't have to worry about that."
"Good point son, good point. You're learning fast!"
