Sink or Swim?

I just ran across this article on drowning. As a parent, it's a bit disturbing (although not as much so as my daughter isn't old enough to swim yet).

But what really bothered me, in reading it, was realizing that back when I took my Red Cross Basic Rescue class (not sure if they still call it that), they only talked about ways to help someone drowning. The topic of recognizing if someone is drowning either never came up, or was talked about as something much closer to what the article describes it not being.
