Well, this supports my own beliefs (coming from the British tradition of keeping one's troubles to oneself), and also a growing body of evidence - spilling your guts (metaphorically speaking) is not necessarily that good for you! A new study of diary keepers found those that regularly kept a diary were more likely than non-diarists to suffer from headaches, sleeplessness, digestive problems and social awkwardness, casting doubt on the cathartic theory of psychotherapy. There's a lot to be said for not dwelling on the past. I think in fact the study is a reflection of the way our memory works - research suggests that people tend to skew events more positively in retrospect, that is, as time goes on, we remember the good things, and lessen the unpleasantness of the bad things. People who write such events down, however, are circumventing this advantageous talent.
