Studies by psychiatry professor show that our psychological defense mechanisms, ways of coping with difficult feelings, become stronger as we grow older. With age we really do cope better with life’s upsets. Actually a physical change in the brain may contribute to this mellowing process. Scientists have been studying a cluster of cells that could be called the brain’s “alarm system”, a center that is involved in arousing anxiety and fear.
