As a young woman, Carolyn Heilbrun made a resolution not to live past "three score years and ten." Taking her own life at the age of seventy, she reasoned, would lend clean closure to a life well lived, and would keep her from the many tragedies of aging--becoming a burden to her children, witnessing the deterioration of her body, falling prey to a crippling disease. But on the advent of her seventieth birthday, she looked back on the past ten years and found, to her surprise, that her sixties had been the happiest decade of after fifty years, her marriage had matured into a happy balance of companionship and respect for solitude; she had developed deep friendships with her grown children and a small circle of peers; she had mastered a highly successful career as a scholar and writer. In the poignant, essayistic writing that best showcases her elegant talent and provocative mind, Carolyn Heilbrun celebrates the many pleasures of a mature life.
