friends are even more important to psychological well-being. Friends bring more happiness into our lives than virtually anything else.
What’s more, friendships have a powerful impact on our physical health. Lack of social connection can be as damaging as smoking, drinking too much, or leading a sedentary lifestyle. Friends are even tied to longevity. A recent Swedish study found that, along with physical activity, maintaining a rich network of friends can add significant years to your life.
