kecerdasan lumba-lumba

So often when we're creating the perfect life, we think about earning more money, having a bigger house, a finer car, and all the accoutrements of wealth and success. As we dream and plan for our tomorrows, however, we must not forget to include time for laughter and playfulness and plain laziness, as well. That's not being silly, it's being "dolphin smart."

"Man has always assumed that he was more intelligent than dolphins because he had achieved so much -- the wheel, New York, wars and so on -- while all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man -- for precisely the same reason."
