Stress is not bad in and of itself. It may help to make us more alert, energize us, or give us a motivational kick in the pants.

For years, actors, entertainers, public speakers, and athletes have known how to turn stress into "high energy" performances. Properly harnessed, stress can indeed work to our advantage at times. But chronic, big-time stress can make us big-time losers...losers of health and wellness.

Aside from taxing the body, excess stress can also tax the mind and lead to poor health decisions, such as the abuse of alcohol or drugs or other self-destructive behaviors.

So the moderate stress is essential for the improvement,isn't it?
