"Absent-mindedness is a boon. It is the quality and trait of professors. It saves us of many inconveniences as we don't either observe or can reproduce. The memory is free of many a baggage as we don't even notice anything or notice irrelevant or unconnected things.
Peace of mind is assured as others don't deal with us in any way as they know we wrongly relate things. Calmness descends in the mind and we can mind our own business without interference from unwanted thoughts, which are triggered from good memory.
Absent-mindedness is guarantees peace of mind to us and our near and dear. Having a good memory with an egoistic mind is inviting mental disturbances. No memory, no thought. No thought, no disturbance.
Long live absent-mindedness!
