My guess would be that Boss Haug likes to go public swimming and uses the need to (learn how to) swim as rationalization for it.
I rarely swim.
But at the Uni, I had a swimming class, and our instructor had sprint competitions during one class. Guess what? I beat a guy and gal who were both on the Uni swimming team. And I never competitively swam in my life, nor did I swim very much before the class.
I guess it's a testament to my natural athletic performance via concentric contractions with which the Lord blessed me.
It was awesome that I beat them. Everyone including myself was surprised. The swimming team members had a dumbfounded expression, but they were gracious about it.
