<p>J’adoube, interesting point. Back in my “Dweck interruption” of the main discussion, I did state that anyone can learn anything at any time. While I am inclined to think that neither Olsen twin could become an Olympic swimmer, before the success of Dara Torres I would not have guessed that a person over 40 could win a silver medal in swimming at the Olympics, let alone three. I do think that either Olsen twin, if she dedicated sufficient time to it, could be a serious competitor in one of the U.S. Masters Swimming age categories. The time devoted is the crux of the issue . . . . but I suppose also the willingness to acquire the body fat to achieve neutral buoyancy in the pool (which seems to be very helpful in swimming).</p>
