Do you know what senescent (zombie) cells are and how cellular senescence and senolytics impact health? In this episode of Longevity by Design, hosts Ashley Reaver and Dr. Gil Blander are joined by Dr. James Kirkland from the Mayo Clinic, one of the world's leading figures in aging research. This episode is a deep dive into aging research, cellular senescence, and senolytics. Dr. Kirkland discusses the impact of cellular aging (senescence) on healthspan and his discovery of the first senolytic agents that remove senescent cells and extend healthspan, illuminating his pioneering work in aging research.
Dr. Kirkland shares insights into the science of cellular senescence and how selectively eliminating these cells could revolutionize the treatment of age-related chronic diseases. He sheds light on the mechanisms behind senolytics and their promise for extending healthspan. The discussion also touches on the importance of lifestyle factors like diet and exercise in managing senescent cells. 
Dr. Kirkland also discusses geroscience, a research paradigm that seeks to understand the mechanisms of aging and how this knowledge can be used to slow the rate of aging, reverse its effects, delay or even cure age-related diseases, and extend healthspan. T Dr. Kirkland also covers the challenges and opportunities in translating these scientific discoveries into clinical applications, emphasizing the critical role of interdisciplinary efforts in advancing our understanding and management of aging.
This is an enlightening episode with Dr. Kirkland on aging research and the opportunities to revolutionize healthcare by combating aging-related diseases and extending people’s health span and lifespan.

Did you know that your oral health has a profound impact on healthspan and longevity?
Do you want to learn about the connections between oral health, healthspan, and longevity and what you can do to improve your oral health to help you live longer and add more healthy years to your life?
This episode of Longevity by Design is an Ask Me Anything (AMA) between Dr. Gil Blander and Ashley Reaver, MS, RD, CSSD, where they dive into the often-overlooked importance of oral health for healthspan and longevity. They gathered and answered questions asked by the Longevity by Design audience, with the scientific evidence indicating that oral health is not just about a nice smile but also has a startling link with healthspan and longevity.
Dr. Gil Blander and Ashley Reaver begin by defining what oral health and oral frailty are. They discuss that good oral health is an essential aspect of overall health and well-being, whereas poor oral health can lead to various dental and health problems. They then answer questions on the oral microbiome and what you should know about it. They also answer questions on how oral health is connected to the health of the rest of the body, healthspan, and longevity–with an emphasis on mortality, Alzheimer’s disease, cardiovascular disease, and diabetes.
Importantly, Dr. Blander and Ashley answer questions backed by science on what you can do to improve your oral health. They conclude by addressing questions on the influence of nutrition on oral health and the not-so-obvious but intriguing evidence on the link between oral health and physical fitness and function.
