     Medical experts have established that there is a direct link between our personality and
better health. According to a new study, the ability of the body to resist some diseases that
are associated with stress is not just a matter of our genetics, race, or gender, but a matter
of our personality.
      The investigators followed 103 adults above 40, examining their personalities and degrees
of extroversion. They found that extroverts (性格外向者)have significantly lower levels of
an inflammatory (炎症性的)chemical that leads to the blocking of arteries(动脉),heart attack
and stroke. They have also found that extroversion is an image of personality which consists
of three parts: a tendency to think in a happy way, a desire to be around other people and a
sense of active engagement with life.
     Though the study was able to show that extroversion and active involvement in life are
associated with lower levels of the inflammatory chemical, it may be really hard to tell which
one comes first. Dr. Chapman warned that the researchers have not discovered yet whether
low inflammation is a result of people's tendencies toward socializing, or inflammation itself is
affecting people by changing their personality tendencies.
     The researchers are not sure how to stimulate people to change their lifestyle or nature.
Physical activity may be a piece of the solution, and has been found to lower stress levels,
especially with aging. Dr. Chapman says that beyond exercise, some individuals just have
this innate (天生的)energy that makes them enthusiastically involved in life. As a result,their
bodies have an increased ability to resist the physical effects of stress.
     The experts arc continuing to try to develop specific therapies, such as the ones  that are
being used to treat depression, and to help people find ways to increase active engagement
in life. Engaging in life can keep people much happier and healthier.
