My hairdresser once told me that he recognized his clients’ vitality or illness by the condition of their hair. Weird but true, we humans are covered with as much hair as gorillas.  The function of hair is to connect us with our feelings.   Sudden fear makes the hair stands up on your arms and on the back of your neck.  When someone you like strokes your arm, warm emotional conductivity is increased through the hair.  We are bodily designed to be in touch.  We are designed to be social beings,  connected to one another.  .
