A psychological and physical response of the body that occurs whenever we must adapt to changing conditions, whether those conditions be real or perceived, positive or negative. Although everyone has stress in their lives, people respond to stress in different ways. Some people seem to be severely affected while others seem calm, cool, and collected all the time. Regardless, we all have it. It's also important to note that there are two types of stress, Eustress (good stress) and Distress (not so good stress).
