And in more ancient days the choices made the  35  between life and death. The crisis we meet today are  36  to be so extreme, but however little the stress is, it requires the same response. It is when such a reaction  37  a long time, through continued exposure to stress, that health becomes  38  . Such serious conditions as high blood pressure and heart disease have established links with stress. 39  we cannot remove stress from our lives, we need to find ways to deal with it.
