"See the plot of the yetzer hara.   In early days, when a Jew became old and his beard turned white, he would recount his deeds and repent his sins.    When he got even older,  he required a cane and that would prepare him for his soon to come Day of Judgment.    But now, young men shave, wear eye glasses and walk vainly with exquisite canes.    Thus, they never come to think of their deeds or do a proper teshuvah!".
