"But the deepest friendships confer the greatest benefits. A sense of being loved, cared for and listened to fosters a sense of meaning and purpose and reduces stress-induced wear and tear on the body, lowering the heart rate, blood pressure and stress hormones, according to research published last month in the Journal of Health and Social Behavior.
