Picture your life. When everything is going fairly well. How much space between your skin and its boundaries? Are you booked to the hilt? What happens when the unexpected stressors hit? A sick child, a death in the family, a redundancy, a relationship break-down? Do you have the wriggle room to absorb some of the shock and stay afloat? Or does the thought of these boulders coming at you make your chest constrict, because you know that if anything else is piled on top of you now, you will go under?
