Yin and Yang in the Animal Kingdom

There are intraverts and extra verts in almost every single species of the animal kingdom. And we need to be adopting much more of a yin and yang approach of balance between the two styles. i want to show you why it is so important that we get that we get to this place of yinan yang, and why we will all be the better for it. To do this, i'm going to start in an unlikely place. I'm going to take you on a very quick tour of the animal world - starting with a colony of fruit flies.
