"There can be no future without a past, because what is to come can only be envisaged as a sort of repetition." – Albert Einstein Our present moment is only meaningful in relation to the past and our expectations about the future. If there was no memory, then the present would be just like the past -- something that always has been and always will be. There could be no anticipation of a better tomorrow because there is no way to know if it will be better or not. Living in the now and not worrying about tomorrow makes sense since there is nothing else to worry about! But while living in the now is acceptable for adults, this mode of existence is difficult for children who are in search of answers about the world and themselves. When you live in the now, you have no idea why things happen as they do. You cannot anticipate what lies ahead because there is no way to know what the future holds. This state of mind is not good for young people who need to understand how things work in order to adapt them to their needs. Children who do not get enough sleep, eat poorly, and/or receive too much stress may suffer from memory loss due to brain dysfunction.
