According to a study published in the Journal of Neuroscience, human memory rewrites the past by adding information from the present. It seems that the new versions that the memory "records" of everything that happens causes emotions that, at the same time, modify again the remembered, so that, as regards what we remember, there is no "original version" .
This study specifically shows that memory is not at all a reliable witness, since it can continually insert elements of the present in the memories of the past when you visit them. It is a survival mechanism, as the study authors count. Memory adapts to a totally changing context, so that this helps us manage what is more important at all times.
So memory is not what it seemed to be. We have spent a lot of time trusting her, boasting her ("I have photographic memory," we say), and it turns out that all this time has been cheating with the present, nothing less. "It seems that it was yesterday," we said when evoking a distant memory. And in reality, not only seems. It was yesterday, maybe even today, when we have finished building, modifying it for the umpteenth time, that memory.
A weight of weight, then, not to live anchored to the past. We know from now that it is not true that all past time was better; Simply, our memory beautifies the past if the present is not what we expected. A reason also to get rid of the grudges, to depart from "I forgive but not forget." It is today's attitude that counts. And with a positive attitude, our memories will even improve.
