The importance of close bonds

According to The New York Times, research shows that close friendships are necessary for optimal health and well-being. A key to close friendship is intimacy, and a big part of intimacy is being able to be fully yourself and be understood by others.
If close friendships really are vital to people’s well-being, one might assume we would be able to make them easily. However, it turns out that the opposite may be true: close friendships are important to people because they are so difficult to form.
