healthy
ill
When you last had a headache: were you healthy or ill then?
Did you go to work anyway that time?
If yes: why?
If no: could your boss have done anything so that you would have come anyway?
And did your headache happen to get worse when you had a quarrel with your partner?
And how did it change when there was an exciting soccer game on TV for example?
If it got better then: Does that mean that your headache was just imaginary? Certainly not!
