We are embarking on a new phase in human history. In both developed and developing countries, population aging has attained unprecedented levels and is expected to continue to do so over the next 50 years. Given increasing longevity and decreasing fertility worldwide, the recent upticks in the proportions of persons aged 65 years and older have been accompanied, in most countries, by steady declines in the proportions of persons aged 14 years and younger. While the magnitude, speed, and timing vary among regions of the globe, population aging has been a reality for decades now. The implications for public health, health care systems, and families are considerable. Indeed, the challenges of an aging society have been thoughtfully articulated and carefully studied, including in the collections of articles on healthy aging that grace past, present, and future issues of the Journal.
What has received far less attention, however, are the opportunities of an aging society for the health of the public. That is why the Commentary by Frumkin et al. (page 1434) devoted to aging, climate change, and legacy thinking is critical to an expansive public health approach that is grounded in social justice and encompasses the health of all generations. The perspective it offers of older adults as a resource because of their concern for legacy—leaving behind an intact world for their children and grandchildren—has resonance for other public health priorities, too.
What are the strengths of an aging society? My own career and personal life are rich with living legacies of older adults who meaningfully contribute to the health of their societies, communities, and families, notwithstanding their own physical limitations. Jack Geiger never ceases to inspire me with his humility and steadfast dedication to human rights and social justice. His leadership and wisdom will be profiled in an upcoming Faces of Public Health column, so the depth and breadth of his influence on global public health are captured in an accessible way for those who have not had the joy of meeting him face-to-face.
In my community-based work in Harlem, New York City, it was the engagement of Gwendolyn Scott, currently the President of Harlem Little League, who made it especially responsive to the needs of the families we served. She was forever being stopped as she walked down the sidewalk by people who wanted to share with her the events of their lives, and she continues to be an avid social networker. Years after we both served on asthma projects through Harlem Hospital Center, I am delighted to remain part of her outreach and receive updates on the health and social priorities of the Harlem community.
Just last week, I received word that my great aunt Dorothy McRae was in failing health. The matriarch of my maternal family, I have never known life without her hustle bustle and generosity of spirit. I called to let her know how much I adored her, but of course, she already knew that. She rallied from a nap to regale me with recent happenings, including the sweet smell of lilacs from the bouquet her daughter had just picked for her. They reminded her of her youth and me of my walk through the park that very morning. I felt in tune with the world and especially with her, despite the time that had elapsed since we last laughed and cried together.
The strengths of an aging society include the mentoring of experienced teachers, the unconditional love of grandparents, the selfless volunteering of older neighbors, and the engaged storytelling of those with the perspective of a long life who care about the health and well-being of everyone in their circle and all who will come after them.
