Imagine that you have an exotic plant that must give bright flowers. For this, it must be watered regularly but not too much, and what is more, it must be placed in a dark place. If you do not water your plant for several days in a row and let the sun rays burn it, the flowers will simply die. Yet it was a very beautiful specimen. This example can be applied to our memory: we all have a brain with this wonderful ability to memorize different information: a short-term memory and also a long-term one. But as the rare plant, this memory can flourish only if we succeed in feeding it properly.
