I see they're making a distinction between young and old here. Hmmmm......there are those folks left over from the 60's who danced their hearts out.
Only about 10 years ago, I was dancing my heart out to worship music. Then I had my accident and lost a joint from my foot. Even after that I danced my heart out one night at a club, just to show the devil that I can still dance. Then I sort of gravitated away from dancing, due to my foot.
