Many people I talk to think stress is bad. That isn't necessarily so.
Stress is an inevitable part of living.
They're not experiencing enough stress. They may even be depressed. It means that your stress level is within a moderate range, not too high and not too low. You're not racing around anxiously and you're not out of gas and depressed. Nor are you stuck in a rut, depressed and anxious, spinning your wheels in futility and frustration.
