How does it feel when I think? Well, the brain is the most complex system of the human body. My thoughts are abstract, random, and sometimes hard to get out of my mouth because they are faster than the way I talk. My brain is constantly firing and they way I think of it is that I am piecing big or small thoughts together to come up with a clear answer. My mind has wires and are all jumbled up but they all come to one outlet where all the processed thoughts come together.
