Love is as critical for your mind and body as oxygen. It's not negotiable. The more connected you are, the healthier you will be both physically and emotionally. The less connected you are, the more you are at risk.
Love is the best antidepressant—but many of our ideas about it are wrong. The less love you have, the more depressed you are likely to feel.
