Aging – Not as Inevitable as You Think

Nir Barzilai, MD, the founding director of the Institute for Aging Research at Albert Einstein College of Medicine, debunks the widespread notion that aging and its consequences are unavoidable. He believes that people can live longer, healthier lives with contemporary knowledge and expertise. Barzilai cites treatments and drugs that identify and may curtail aging’s causes and increase people’s “health span.” He encourages readers to prepare for healthy lives in their 90s and beyond. The book – Age Later – is receiving positive reviews. Dr. Barzilai is regarded as one of the best science communicators globally, and his work is of interest to everyone concerned with the overlap between health and aging.

Unlock the Secret of Aging

Dr. Barzilai delves into the science of aging and the importance of addressing age-related illnesses. He emphasizes the collaboration between geroscientists and specialists in enhancing the quality of life for the aged. Aging is caused by the body’s natural wear and tear, yet genetics play a vital role in how susceptible one becomes to illnesses as they age. By comparing animal aging to that of people who live a healthy, long life, Dr. Barzilai aims to unlock the secret of aging slowly. He also advises on the importance of exercise, moderation in drinking and eating, maintaining friendships, and purpose.

Breaking the Code of Aging

The pursuit of longevity is not new but now scientists have succeeded in identifying the processes that drive aging, which can be targeted to extend healthspan. Dr. Barzilai, a geriatrician, reveals that growing old healthily is possible with drugs already in use today, especially Metformin. Factors driving aging include inflammation, immune dysfunction, and senescence of cells. Aging’s economic burden can be countered with improving healthspan.

Dr. Nir Barzilai, a renowned geriatrician, offers insights into how aging and longevity research is revolutionizing healthcare. The pursuit of longevity is not new, but what is new is scientists’ ability to identify the processes that drive aging and improve healthspan. In his book, Dr. Barzilai explains that geroscientists are seeking a pharmaceutical solution to the hallmarks of aging, which include inflammation, immune dysfunction, and senescence of cells. Growing old healthily can be achieved with drugs already in use today, especially Metformin, a drug predominantly used to treat Type 2 diabetes.

Dr. Barzilai discusses the economic and human impact of age-related illnesses and the growing burden on healthcare services. He reveals governments, healthcare providers, and human service providers worldwide are seeking ways to deal with the problem. However, he posits good news for societies concerned about medical expenses incurred by aging populations, as healthier, longer lives mean fewer individual and collective costs.

This book provides insights into aging, which is a natural and unstoppable process. Nonetheless, geroscientists are identifying the underlying sources of aging and developing “designer drugs” to target them. Dr. Barzilai’s books offer hope for a future where pre-teens today may eventually know their great and even great-great-grandchildren.
