We tend to mull over the bad things that happen to us than ponder on the good ones. Studies in psychology theorise that negative events, which trigger a "fight or flight" response, cause more heightened activities in the regions of the brain that deal with emotions - the frontal lobes and amygdala. The more negative the events, the more activities in these regions; hence, the more indelible the memory and negative recall.
