"Aging is a process, an accumulation of deficiencies which starts right from the middle age"
The precise distinguishing set point is not present for aging.
The above definition sets an alarm in my brain that, it's not only our physical body but the psychic part also undergoes aging. But the startling difference is that this deficiency in thinking proceeds right from our childhood. The extraordinary will present in every child is tampered at every stage. A child grows up with the accumulation of these limitations to end up as an adult who is always afraid of chasing the dream and being content with the circumstances.
