Not many people know that the mind is a harvest of cells, that store data of genetics and information regarding growth through the years.
It is simply a large database for ones learning. And it can store a lot of info, meaning the five senses. Visual, Audio, Touch, Smell, Taste.
But whilst we are growing up, the mind needs to store this data, in either the temporary part of the brain and only to retain key points made throughout the day. These key points are bits that the person or animal, insect, needs to remember. Like walking, if we did not keep this information, then we would need to learn to walk each and everyday.
But it is the information that is in the temp lobe, that secretes and deletes the data that is not needed.
So the mind has its drawbacks as it cannot backup and cannot be backed up, in everyday usage.
