Stress is a part of our lives, regardless of age, race, or gender. The 5-year-old anticipating his or her first day of kindergarten feels stress. The anxiety associated with stress is relative to the person having the experience.
Repeated exposure to stressful events can lessen the effects on our brains and our bodies, much like a rehearsal prepares actors to take the stage. A routine public speaker is far less stressed about a presentation than, say a high school valedictorian is about speaking to his or her classmates.
