Remember what you had for breakfast exactly one month ago? Probably not, but ask Bob Petrella and he’ll tell you what he ate, the conversations he had and what the weather was like (see box below).

Two new studies attempt to establish just what underlies this extraordinary power of recollection. The results could eventually help people with anxiety and depression, and help us all remember our past a little easier.
