Hugging is good medicine. It transfers energy, and gives the person hugged an emotional boost. You need four hugs a day for survival, eight for maintenance, and twelve for growth. A hug makes you feel good. The skin is the largest organ we have and it needs a great deal of care. A hug can cover a lot of skin and gives the message that you care. It is also a form of communication. It can say things you don't have words for. The nicest thing about a hug is that you usually can't give one without getting one.
