When did stress become the excuse for everything that goes wrong in a person's life?
Pinpointing that exact moment is impossible -- it is sufficient to say that stress has become a modern crutch on which to support actions that in earlier years would have had no such explanation or excuse.
The phrases are common -- stress in the workplace, stress in marriage, stress in the classroom, stress on the playground, stress at the day-care centre, stress on the playing field, stress at church.
