In the coming years, it is anticipated that more individuals will reach the remarkable ages of 100, 120, or even 130 years, ushering in a new era of human longevity. However, this extended lifespan might not align with our conventional expectations of ageing.
In a trailblazing exploration of this phenomenon, acclaimed author Michael Roizen reveals how modern science and technology could revolutionise our ability to live longer, healthier lives. This review delves into Roizen’s book ‘The Great Age Reboot,’ exploring the exciting prospects and far-reaching consequences of this imminent age transformation.

What is the book about?

‘The Great Age Reboot’ by Michael F. Roizen explores the remarkable advancements in modern medicine and science, which are leading humanity into a new era of extended and healthier lives. Dr. Roizen paints a vivid picture of how the world has rapidly evolved in the past century, with innovations like antibiotics, immuniіations, and cutting-edge surgical techniques, such as MRI-guided robotic surgery.
The central premise of the book revolves around the concept of the Great Age Reboot. Dr. Roizen predicts a near future marked by extraordinary scientific and intellectual breakthroughs that will revolutionise the way we age, live, and interact with our world. These transformative changes are expected to significantly extend human life expectancy, with projections suggesting that people over 40 today may have an average life expectancy of at least 108 by 2030. This shift represents an unprecedented 1,100 per cent increase in life expectancy gains over the last century.
Importantly, the book emphasises that this extended lifespan won’t equate to simply growing older but rather to enjoying more ‘prime-living’ years. The typical 95-year-old in the near future may exhibit the vitality and functionality of a 50-year-old today, provided they make favourable health and lifestyle choices.
Overall, ‘The Great Age Reboot’ encourages readers to embrace the incredible changes on the horizon, take steps to prepare for a longer and healthier future, and actively engage in shaping a society that embraces the concept of ‘young old.’

Three key takeaways from ‘The Great Age Reboot’

1By reengineering ageing cells, human life expectancy may be extended
Michael F. Roizen explores the groundbreaking potential of senolytics, a cutting-edge medical approach that targets and eliminates ageing cells, known as senescent cells, to rejuvenate the body. Drawing parallels to a magical elixir that restores youth, Roizen describes how scientists have been working on using senolytics to slow down ageing processes and mitigate age-related diseases. Promising experiments, such as the injection of senolytics into arthritic knees, have shown remarkable results in reducing pain and inflammation, challenging the notion that certain conditions are inevitable consequences of ageing.
Moreover, senolytics hold the promise of not only improving joint health but also potentially rejuvenating other organs and systems, including the heart, brain, and eyes. These interventions may enable individuals to extend their youthful vitality and overall health, ultimately reshaping our understanding of ageing and its associated challenges. While challenges remain, including considerations regarding cancer and autophagy, the potential for senolytics to revolutionise the way we age is both exciting and promising, offering the hope of a healthier and more youthful future.
2Age-related damage has the potential to be reversed with the use of epigenetic rejuvenation
In ‘Your DNA Destiny, Edited,’ Michael F. Roizen delves into the fascinating realm of genetic engineering and epigenetic rejuvenation. The chapter emphasises that while our genetics play a role in our health, epigenetic switches can control which genes are active or dormant, allowing us to influence our genetic destiny through lifestyle choices. The introduction of CRISPR/Cas9 technology, likened to biological scissors, holds the promise of addressing genetic defects and diseases, potentially opening the door to treatments for conditions like Alzheimer’s and cancer.
Moreover, the concept of rebooting or resetting epigenes to their youthful state offers the prospect of extending our vitality and reversing age-related damage. Scientists have made remarkable progress in reprogramming genes in animals, raising hopes that similar advancements could be applied to humans.
Ultimately, Roizen highlights the evolving understanding of genes and their malleability, paving the way for a future where individuals have the power to edit their genetic code, influence gene expression, and rewrite their genetic destiny. As society grapples with ethical questions surrounding gene manipulation, the potential for healthier, more vibrant, and longer lives through genetic engineering remains a tempting frontier in the quest for longevity.
3You have the ability to optimise your health and raise your chances of longevity via healthy lifestyle choices
Aside from presenting fascinating methods of cellular reprogramming, the author also emphasises the importance of shaping our responses to life’s challenges, concentrating on ‘self-engineering’ the brain, heart, and immune system for a longer life.
The book highlights the crucial role of a strong circulatory system and effective stress management. Stress reduction activities are shown to have significant benefits, improving markers for heart disease and brain-related issues. Exercise is lauded as a potent tool for enhancing both brain and heart function, with detailed guidance provided on beneficial workout routines. Dietary choices, particularly a Mediterranean-style diet, are emphasised to reduce the risk of cardiovascular disease and dementia while cautioning against inflammation-inducing ingredients like added sugars and saturated fats.
The book’s second major focus centres on immune system self-engineering, vital for defence against aggressive diseases. It advocates for a diverse intake of micronutrients, protein-rich foods, and limiting added sugars and simple carbs. Vaccinations, supplementation, and stress management techniques are also highlighted as essential components of immune system optimisation.

Best quotes from ‘The Great Age Reboot’

“Do not get hung up on the past. Your life is made up of the present and future, and your past helps you navigate.”
“The gene editing and the epigenetic on-and-off technologies are not perfect, but they are improving. About 10,000 diseases are caused by a single error in a single gene. In theory, we should be able to eliminate every one of them through gene editing. If you know the gene and the error, you can get rid of it.”
“There is, of course, a cloudier side of increased longevity. While the benefits of wise decisions grow, the costs of unwise decisions also grow. This dichotomy will create greater disparities in health, income, and wealth if we do not address it over time. The longer we live, the more the decisions we have made regarding our work, savings, and health compound the advantages and disadvantages we experience in our later years.”
