HEAD.

The title.

Well the one one reason that we are so far ahead of our colleagues (by colleague I mean the other animals we share this planet with), is that we have a hugely superior brain and one that has propelled us to the tip of the food pyramid and made us masters and decision makers of this planet.
And its not just that.
The emotions that we feel, the thoughts that we experience are far more complex than anyone else. Our mind gives us a sense of judgment, a conscience to choose between what we believe at that point of time what is right or wrong, and the sheer power to live life the we want to. Even when we talk of our heart, it more like another corner of our infinitely huge HEAD.
"Its all in the head people, its all in the head"
