Lifespan: Why We Age―and Why We Don’t Have To:

TL;DR Summary

What if I told you that aging is a disease, and like many diseases, it's one we can treat, and even reverse? Welcome to "Lifespan: Why We Age―and Why We Don't Have To," where we embark on a journey through the past, present, and future of aging research. In this revolutionary exploration, I argue that aging is not inevitable; it’s merely a biological process that we can slow down, halt, or even reverse. Backed by cutting-edge scientific research and firsthand experiences in the lab, we delve into the mechanisms that contribute to aging, such as epigenetic changes, and decode them like flipping switches in an electrical circuit.

We unravel the Information Theory of Aging, positing that aging is less about the wearing down of the body and more about the loss of information at the cellular level. Imagine DNA as music and aging as the scratches on a record; the right tools could "smooth out" those scratches, restoring the original music. What’s more, we take a look at the technologies and innovations that make this transformation possible, from CRISPR to NAD+ boosters. At the intersection of biology and technology, we find the keys to unlock a longer, healthier life.

But we don’t stop at the science. We confront the ethical, societal, and philosophical questions that come with extended life. Who gets to live longer? How will society change when 100 is the new 60? It's not just about extending our lifespan; it's about extending our healthspan. By the end of this enlightening tour, you won't just see aging as a fact of life; you'll see it as a challenge—one we're well on our way to conquering. Buckle up; you're in for an eye-opening ride that could quite literally add years to your life.

Lifespan: Why We Age―and Why We Don’t Have To:


Information Theory of Aging: The theory posits that aging isn’t about the simple wear and tear of cells but is about the loss of cellular information. We discuss the analogy of a scratched record losing its original music over time, linking it to how cellular information can be restored.

Biological Mechanisms of Aging: We examine telomere shortening, mitochondrial dysfunction, and other biological processes to understand how they contribute to aging. For instance, we talk about NAD+ and its decreasing levels as an age-related phenomenon that impacts cell function.

Technological Innovations: Technologies like CRISPR and advances in AI for drug discovery are highlighted as tools that can potentially reverse aging. We mention specific cases like the use of CRISPR to edit genes responsible for age-related diseases.

Ethical and Societal Implications: Questions about who gets access to these therapies, the impact on population growth, and resource utilization are discussed. We ponder on the societal changes when people start living significantly longer and healthier lives.

Healthspan vs Lifespan: The focus is not merely on extending life but improving the quality of life in the years we gain. We discuss interventions, like calorie restriction and intermittent fasting, as ways to improve both.
