A hug

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;
