Anger is not all bad. On occasion, history has seen thinkers and leaders venting this primitive emotion to society's betterment. But in its mundane expressions--engaging in acrimonious interpersonal relationships, flying off the handle, "seeing red" or frequently resorting to verbal or physical abuse--anger can be the most counterproductive emotion in the human breast.
If anger is seldom bridled, says Weisinger, who has a Ph.D. in psychology, it can be the primary factor in obesity, sexual dysfunction, migraine headaches and ulcers. Angry people tend to lose their jobs and friends, are prone to disease and suicide and a whole lot more.
