The Short Answer

For good recall, memories need to be recalled. Huh? Memories are reinforced the more they are accessed. In fact, there's evidence that when you remember something, the memory is accessed and mostly erased, then re-written. If you don't access a memory, it tends to fade away. But accessing it will refresh it and bring it back to near-original strength. The downside of this is that we don't really remember events. We remember our *memories* of the events. This can make human memory fickle, as we can introduce changes in what we remember, but be absolutely convinced that it is what actually happened.
