You know you're under stress when you rear-end the car in front of you on the way to work (oops!), make it to work three hours late and get fired (no!), then have your wallet stolen on the bus ride home (oh, that's just perfect!). But what about when you get engaged to the love of your life? Or, when you finally get the promotion of your dreams? What about when you have hay fever, or move into a new home, or adopt a dog? Is it stressful to graduate from college, or start an exercise program, or binge on chocolate chip cookies? You bet it is.
