Something's got to give. What? What do you expect to come out of this study? The study itself is nothing; what's done about it, and by whom, is the part that concerns me. If parents don't want their kids to learn to swim, THAT'S THEIR RIGHT. Many parents don't want their kids learning how to drive until they're 18 or older, and I think that's a serious detriment to their learning how to drive *well* at any age. But I'm not going to tell those parents that they have to do things my way. They made their choice, and the kids have to live with the consequences. That's how life works. There's nothing from stopping the children from learning swimming (or advanced driving) later in life; so it's a bit harder, it's still possible and they'll know not to put their own kids through the extra effort. Social evolution.

The rest was addressed in my response above.
