If people are allowed to live their sexual life joyously, by the time they are nearing forty-two — remember, I am saying forty-two, not eighty-four — just when they are nearing forty-two, sex will start losing its grip on them. Just as sex arises and becomes very powerful by the age one is fourteen, in exactly the same way by the time one is forty-two it starts disappearing.  It is a natural course.
