Probably the mind behaves differently. It may also have likes and dislikes. The matters which are not liked by our mind may go to waste bin easily. But matters which are liked by the mind will be stored in the memory. Taking the issues from the waste bin back may be difficult.
The lesson we studied in our high school and primary school may be remembered for a long time. But we remember the fights we have with our friends and the movies we have seen by bunking the classes will be remembered. Maybe that is the attitude of human minds.
Knowledge is power.
Believe in the existence of God the super power.
