The old thinking: Getting angry is unhealthy because it raises blood pressure (hence expressions like "that makes my blood boil").
The new wisdom: As long as your anger problems aren't chronic, getting mad when you face an unfair situation can actually buffer stress.

Reacting with controlled anger rather than runaway anxiety releases less of the body's stress hormone cortisol—too much of which has been linked to bone loss, depression, and obesity.
