In my unpublished novel, A WALK ON FIFITH AVENUE, Professor Arzzuro, a brain surgeon, is poised to discover the mechanism of aging, which would make it possible for people to live two-three hundred years or more. In fact, who made us live about 70-80 years? Perhaps, God. Somehow, aging is regulated by different mechanisms; some cosmic, some of a different nature. For all the beings on earth, the information necessary to control these mechanisms is written somewhere in the genetic code. Professor Arzzuro believes that some regulatory centers are located in the brain, and, almost retired, he tries to decipher that mystery of life.
