There was an interesting report on NPR today about the changes in the brain that occur when we connect with people.
The changes are measurable and can contribute to a greater sense of joy. Something similar occurs when we are involved in social media relationships, but to a lesser degree. Yet social media involvement taps into the brain pathways that lead to addictions. While I fully grasp the realities of introversion and extroversion, I am convinced that being with people is essential for a life that is full. I am currently reading a book that suggests that the creation of social infrastructure (read farmer's markets, bike paths, libraries, pubs, parks, museums) is a way for all of levels of government to aid us in getting together. Connected lives are fuller and, I believe, happier lives.
