I understand the physiological mechanism that gives rise to goosebumps in
response to positive or negative stress.  But why did we evolve such a
mechanism?  Much of the feeling is internal, so it was not just to make hair
stand up.  We evolved feeling pain to protect us; why have we chills --
especially in response to something positive?
