geographically stable individuals

Type A Behavior Pattern
A behavioral and emotional style marked by an
aggressive, unceasing struggle to achieve more
and more in less time

individuals or forces
a risk factor for coronary artery disease
Hostility appears to be especially implicated as
the risk factor

frequent anger, antagonism, distrust of others
