My family are huggers - they hug to say hello and they hug to say good-bye.  These last few years I've come to appreciate a hug.  It relieves pain, suffering, depression and loneliness.  It gives me a feeling of belonging, eases my fears and builds my self-esteem, and its free for the taking. So, hug the people you care about because what you give in this case - you also receive back.
