Now we have to realize that the uphill period of life is epitomized by the operation of the enhancer regulation that maintains the basic activity of the brain on a significantly higher level (Knoll and Miklya 1995). The period of enhanced activity lasts until sex hormones appear, dampen enhancer regulation, and lower the basic brain activity to its preweaning level (Knoll et al. 2000). Thus, sex hormones provide for the transition from the developmental phase of life to postdevelopmental longevity, the period of the slow age-related decay of brain performance and terminated by natural death. 

How can youth be defined how long does it last how is it terminated Or, using a more scientific sounding terminology what is the essential difference between developmental and postdevelopmental longevity what is the cause of the transition from one phase to the other ... 

For the time being the prestigious task - the maintenance of mesencephalic enhancer regulation during the postdevelopmental phase of life on the enhanced level characteristic of developmental longevity - cannot be fully accomplished. Fiowever, it is already feasible to modestly slow the age-related decay of the catecholaminergic and trace-aminergic tone in the brain via the prophylactic administration of 1 mg (-)-deprenyl daily.
