ABSTRACT

It is unfortunate that one of the most common sensations known to humanity is also one of the least understood. Besides love, throughout history there has been no other motivator stronger than pain. Pain can change one’s life in an instant, completely turning the direction of an individual’s course and those with whom he or she comes into contact. Pain, or the avoidance thereof, whether physical, psychological, or emotional, motivates every living entity from humanity to single cell organisms.
