Most definitions of short-term memory limit the duration of storage to less than a minute: no more than about 30 seconds, and in some models as little as 2. In order to overcome this, and retain information for longer, information must be periodically repeated, or rehearsed either by articulating it out loud, or by mentally simulating such articulation. In this way, the information will re-enter the short-term store and be retained for a further period.
Having said that make sure the retained info is worth all the trouble !!!
