Our Battle Against Middle and Old Age is a pioneering guide to aging with vitality, written by Dr. Nestor Maria Gustilo, one of the Philippines’ early voices in geriatrics and gerontology. Blending medical insight with compassionate, practical advice, Dr. Gustilo explains the science of aging and empowers readers to add not just years to their life, but life to their years. Drawing from decades of clinical experience and international engagement, he demystifies the changes that come with middle and old age and offers strategies for maintaining health, dignity, and purpose. Both educational and encouraging, this book stands as a reminder that longevity is not simply a matter of fate—it is a daily commitment to living well.
