Remembering is mind-wandering into the past. We can also wander into the future, imagining what might happen tomorrow, or next Christmas, or when the Antarctic ice melts. The evidence shows, in fact, that people spend more time thinking about the future than about the past.  Nevertheless, there is a natural continuity between future and past, as time glides relentlessly from one to the other. What we’re about to do quickly becomes what we have done -assuming we actually do it. Sometimes we don’t, and when that happens we’re inclined to say: ‘Well I forgot.” Even forgetting, it seems, can apply to the future as to the past.
