I first studied psychological science in the 1970s, and one of the most popular ideas at that time was the Type A personality.

The early research raised more questions than it answered, notably: How, precisely, does a pattern of behaviors cause the physical changes that culminate in cardiovascular disease? Can these traits and behaviors be changed, with reduced heart risk? Where does Type A originate? Do harmful Type A behaviors vary across gender, race and culture?
