At twenty-nine, the ticking of the biological clock becomes especially unnerving for many a woman and she begins to worry about time running out on her. In this day and age, with modern medicine retrieving the most fragile of fetuses and menopause taking its merry time about showing up, women could wait until thirty-nine to get panic-stricken, but the symbolic significance of twenty-nine has not loosened its hold on us yet.
