Short summary

David A. Sinclair, PhD, is an Australian biologist who is a professor of genetics and the co-director of Paul F. Glenn Center for the Biology of Aging. His work is mainly centered on understanding aging, and he has received many awards for his dedicated efforts in the field. While we know that all living things must eventually die, we don't know why, but we accept it nonetheless. Sinclair goes a step further and peeks beyond the curtain to reveal to us just what aging is, what causes it, and how to, in theory, eradicate the need to age in humanity. Aging is inevitable, but it feels like we've become too comfortable with it. Maybe we should question it more and find out if it's possible to stop it without any side effects. “Aging, quite simply, is a loss of information.” ~ David A. Sinclair, PhD

Aging is the deadliest disease humanity has to battle

Listen the first key point
00:00
00:00
While humanity battles with a vast array of deadly illnesses such as cancer, HIV, and heart diseases, these might be the least of our worries. Sinclair believes the real enemy, the one condition we should focus our efforts on, is aging. Our existence is constantly plagued with the ever-present problem of growing old.
Aging might be a more present danger to our existence than most common diseases.
We have refused to relent in our fight to find cures or workable management treatments with other illnesses, but somehow, we have accepted that aging and expiration are normal. However, with all our efforts to fight diseases, we cannot indefinitely protect all humanity from ALL of them.

The scientific community, Sinclair bemoans, has failed to acknowledge aging as a severe disease and, as such, has exposed us to more fatality than that which we face from other recognized diseases. If we can understand the science of aging, we can unlock the secrets to a longer, healthier life.
If we can cure aging, we would have eradicated the main plague humanity battles with.
We often look to eradicating diseases as the key to longevity, but we might be attacking the enemy with the wrong approach. Humanity, free from infection, will still suffer that same dreadful fate; death; that is why solving the aging crisis is the best bet to getting ahead of the ticking clock that is our existence. In the following chapters, we shall explore the genuine concept of aging and how we can effectively slow it down and even reverse it.

Here, Dr. David Sinclair, the world's leading authority on genetics and longevity, reveals a groundbreaking and novel theory for a reason all humans age.
Aging is a disease, and all diseases are practically treatable. ~ David Sinclair, PhD
This summary takes readers to the forefront of research from Dr. David Sinclair's lab at Harvard—that demonstrates how we can reduce or even turn the hands of the clock back on aging. The key to this claim on immortality is the activation of newly discovered genes known as vitality genes. These genes result from a much older genetic survival framework that causes aging; it is also the key to reversing it.
second key point

It is essential to understand the root cause of aging in humans if we are going to combat it

To understand aging, we must first uncover what causes it. If aging is constant and present in all life forms, then there must be a reason that both sets off and perpetuates it. Without ample knowledge of the disease and what triggers it, we will be largely unable to prevent or cure it.

Headway is the answer! No longer accumulating books I never read. With Headway, I initially chose the areas important to me such as productivity, time management, etc., and each day I'm provided several book summaries from which I devote 20 minutes or more each day reading. All of this on my phone! My life has improved with Headway. Truly my most useful app.

In today’s world, we rarely have time. Between our jobs, our families are social obligations, when do we have time to grow and develop ourselves? Headway is an excellent app that gives you that time it gives you those little snippets of information that you need to direct your focus in on your life. Headway gives you a chance to find out the meat of a book that you might want to purchase and read or listen to in-depth without wasting a lot of time trying to figure out is this book for me? I highly recommend the app.

I've gotten multiple books out of the library with the intent to read them, but always have a hard time finding the time. This app has helped me finally be able to get to them. Summarized, yes, and thank goodness too! Just short enough I can finish one on my way picking kids up from school/practice, or while I'm cooking dinner. I can't wait to listen to them over the summer when we visit the beach!

It amazed me! There is the possibility to highlight the most important points of each book and instantly translate unfamiliar vocabulary. With the ability to review the searched words. It's a great way to learn more about English as well. The price is great.

I’m enjoying what I’m learning on headway.each summary comes with quotes at the end which you can save to help you remember key points. You can listen or read, I’ve found that reading puts me to sleep before I can finish but the listening feature keeps me engaged and I can finish in a brief amount of time if not one session.

Exactly what I need! I always have booklist to read, but can't committed enough to finish/start bc of too much pages. Headway is really helpful and concise with their summary. What I love the most is that the essence of the book is well crafted, so I don't only read the key points, but also there's the story and how personality of the author still well shown through the summary. Well done!
