Fit to dance?

Now I have never been a natural athlete. Even now when I am probably the fittest I have been for twenty years, you would not call me athletic.
There is however a fitness associated with dancing. It is a fitness unlike any other, it involves the way we hold our bodies up, the ability to move in a way unlike any other and a degree of flexibility that involves completely different parts of the body.
It must do us a lot of good though. Have you seen how many octogenarians are still dancing? It keeps them fit and active and it is not unusual to see men in their nineties still cutting a rug in Buenos Aires, and making us relative youngsters look positively pedestrian.
Recently we have had a new student here at Gresford, a tri-athlete no less. Now I know I would be a mess if I ever tried running swimming and cycling in quick succession, so obviously he is far fitter than I am. Never the less at the end of an hour’s lesson he is reduced to a sweaty mess. He says he never realized it would be so hard.
It does my ego some good to think someone who is so fit cannot keep up with me; I am tempted to say “keep up pussy” but then he may just challenge me to a triathlon in retaliation. Perhaps it is best I keep my mouth shut.
