This article was inspired by the many reasons why i love the brain and all of its features.  I have always wanted to specialize in this area because of its complexity and mystery ever since I was in grade 5.  This article is based off just a fraction of what the brain has to offer.  Some of the brain hasn't even been discovered yet.  The reasons I picked social interaction over everything else about the brain is quite simple.  It's because we used it as a survival tactic in the past,  It is vital to us, we suffer without it,  and our entire society is built of this mere need to communicate.  Social interaction has been embedded in all lives since the beginning of time. If that’s not important stuff I don’t know what is.
