¿Y si envejecer fuera una enfermedad y fuese tratable como tal? Un aclamado científico de la facultad de Medicina de Harvard y una de las personas más influyentes según la revista Time. Que envejecer es inevitable es una verdad aparentemente innegable. pero, ¿qué pasaría si todo lo que se nos ha dicho hasta ahora sobre el envejecimiento resultase incierto?, ¿qué sucedería si pudiéramos elegir nuestra esperanza de vida? En este libro innovador y asombroso, el Dr. David Sinclair, autoridad mundial y líder en genética y longevidad, revela una nueva y audaz teoría. Como él explica, el envejecimiento es una enfermedad y es una enfermedad tratable. Experimentos recientes en la reprogramación genética sugieren que, en un futuro cercano, no solo podremos sentirnos más jóvenes, sino serlo. Mediante estas páginas, el Dr. Sinclair nos invita al proceso de descubrimiento científico y revela algunas tecnologías emergentes y algunos cambios simples en el estilo de vida que nos ayudarán a sentirnos más jóvenes y a estar más saludables por más tiempo como el ayuno intermitente, la exposición al frío, hacer ejercicio con la intensidad adecuada y comer menos carne. Alarga tu esperanza de vida cambiará para siempre nuestra idea sobre por qué envejecemos y qué podemos hacer al respecto. ENGLISH DESCRIPTION A paradigm-shifting book from an acclaimed Harvard Medical School scientist and one of Time's most influential people. It's a seemingly undeniable truth that aging is inevitable. But what if everything we've been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: "Aging is a disease, and that disease is treatable." This eye-opening and provocative work takes us to the frontlines of research that is pushing the boundaries on our perceived scientific limitations, revealing incredible breakthroughs-many from Dr. David Sinclair's own lab at Harvard-that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it. Recent experiments in genetic reprogramming suggest that in the near future we may not just be able to feel younger, but actually become younger. Through a page-turning narrative, Dr. Sinclair invites you into the process of scientific discovery and reveals the emerging technologies and simple lifestyle changes-such as intermittent fasting, cold exposure, exercising with the right intensity, and eating less meat-that have been shown to help us live younger and healthier for longer. At once a roadmap for taking charge of our own health destiny and a bold new vision for the future of humankind, Lifespan will forever change the way we think about why we age and what we can do about it.Shipping Notes

In Kathy Koch’s Words, “To get something new, you must do something new.”
Format: Paperback
Dr. Kathy out did herself with this one. I finished the book with hope, ideas, and actionable steps, to use in my relationships with my adult children.
She repeats this phrase throughout her book, “To get something new, you must do something new.” I like this so much more than the definition of insanity, “doing the same thing over and over again and expecting different results," (not sure who said it first and it is not my definition). I am a creature of habit and do the same things and can be amazed when nothing changes. But as Dr. Kathy states I have to do something new, and this book gives me that new. Every chapter ends with 5 actionable steps, and guided activities to apply what was discussed. Some steps are even scripted to help when you don’t know what to say.
I have 13 children. 6 have reached adulthood. 4 of them are married and we have 10 amazing grandchildren. Navigating relationships with the adult kids sometimes feels like a roller coaster ride. I can be passive aggressive and opinionated. I know better, but bad habits are hard to break.
When I got the email that this book was about to be published and Dr. Kathy was looking for some to read and give an honest opinion of it, I jumped at the chance. I received a free digital copy, and as soon as it was available I bought it.
I highly recommend this book. It was written to help with adult kids, but you can apply the ideas with communicating with any adults or even kids.
Chapter 1 “First, The Basics” as our children become adults we are their parents (noun), but are no longer to parent (verb). Our role switches to encourager, guide, counselor, coach based on mutual trust. She reminds us that our purpose is more than just parenting. She discusses the 5 core needs of security, identity, belonging, purpose, and competence. She even gives a scripted Declaration of Release returning our children into the hands of an all powerful God.
Chapter 2 “Look Honestly at Yourself” Dr. Kathy hits hard here. She tells us to lose our pride, take responsibility for our part and be open to make changes. She also tells the reader to listen to learn and not to judge. This chapter gave me so much insight into my personal relationships. Reminded me that I get defensive because I don’t want to be criticized or blamed. She guides in ways to get to the bottom of hurts by asking questions and listening.
Chapter 3 “Listen More, Talk Less” No unsolicited advice. Listen to understand. Ask questions to clarify, and ask permission before giving your two cents. Hear your children. Love them. Accept them. This doesn’t mean you like or approve their choices, just acknowledge it. Focus on the present. Facts. Surrender it all to God.
Chapter 4 “How to Handle Grief So It Doesn’t Handle You” Acknowledge grief, give yourself time to accept and grieve. Grieve what isn’t and accept what is. Reject lies and embrace truth. Then work on what you can.
Chapter 5 “The Two Shall Become One” has all the tips for when your adult child marries. How to handle traditions, holidays, etc.
Chapter 6 “The Blessings of Grandchildren” has my next favorite quote. Dr. Kathy says, “Don’t judge past by today’s wisdom.” This gem is one I have repeatedly told myself since I finished reading the book. I did the best I could at that time. I have grown, matured, learned more, and am not the same person I was. She also says that God calls me to love others, not analyze and fix them. So now that the grandchildren are here I need to learn their 8 great smarts (word, logic, picture, music, body, nature, people, and self), be active and not idolize.
Chapter 7 “Close or Far away” we need to respect their home and ways. Always ask to stop by and leave judgement at the door. Instead of walking in and feeling like you should do something, instead ask “What would you like me to do.” My job is to pray and serve.
Chapter 8 “The Big Stuff:Moving Home and More” addresses the need for clear communication, clear expectations and respect.
Chapter 9 “ Politics, Lifestyle, and Other Hot Topics” Bottom line is to be open and approachable. If a topic comes up that can’t be discussed peacefully it is ok to say no to discussing right then. Always be respectful and stay calm.
Chapter 10 “The Prodigal” This one leans a lot into giving up our control and leaning into God’s sovereignty. Releasing. Grieving. Loving unconditionally. Being available to listen, but not quick to solve, and offer unsolicited advice.
Chapter 11 “Finding Hope When Life Unravels” where does our hope come from? The Lord. We cannot live in past guilt and shame. Know you did the best you could. If you did wrong, take responsibility for it. Ultimately though it is all in His hands. Sometimes we have to get out of the way and let God work in our children’s lives. We can’t. But He can. Trust in His sovereignty.

A thoughtful and practical book, from an author we have trusted through all the stages of parenting!
Format: Paperback
When we started our family, we figured that the "hard years" would be the ones with night-time feedings, teething, potty training... As my mom later revealed, "little children, little problems...big kids, big problems." And now, as parents of 4 adults, our learning in this "parenting stage" continues, and we appreciate all the help we can get! (And we now have lots of grandkids...a whole new phase with a steep learning curve!)
We met Dr Kathy years ago, at a homeschooling conference in Europe, and have closely followed her ever since. She was a huge help to our oldest who was struggling in the German school system. When we were asked if we would like an advance copy of her book about strategies as parents of adult children, we were very glad to say yes!
We so appreciate her thoughtful, practical advice! This book is filled with both, and we plan to get a hard copy, to re-read and underline. And we are definitely glad to recommend it to friends in this stage of life, whether they have great relationships with their kids or ones with tough challenges.

Practical help for a challenging transition of parenthood
Format: Paperback
I have long been a fan of Dr. Kathy, having read several of her books as well as heard her speak at conferences. She is always down to earth with practical ideas and spiritual truths. I was provided an advance, free copy of this book to read and preview, and I must say it was such as relevant topic to me - I have two young adult children, one who is fully launched and one still at home. Full disclosure - I am only through chapter 3, but that is because I wanted to take my time and digest the applications of this book!
Some ideas I am already contemplepating and implementing:
- avoiding placing my child (and their happiness) as a sort of idol in my life
- an echo of what I'd already sensed - I need to shift my role from parent to invided guide
-humbly confronting my own assumptions and beliefs as a pathway to open dialog
- tackling the hard work of bcoming an active, intentional and sensitive listener.
I had a digital copy so underlining wasn't practical, but that may be good as I'd want to underline most of the book so far! Each chapter has a mixture of concepts, ideas for building skills in real life and suggested prayers. I can't wait to finish the book - I actually ordered two hard copies for my husband and I to read and discuss together.
Thank you for this book!

I will read it again and refer to it often.
Format: Paperback
"I hope and pray that what I've written has been what you needed - comforting, relevant, and appropriately challenging insights and ideas that will guide you to have more peace, hope, and growth. I picture you feeling differently, thinking differently, and using new ideas for God's glory. " Dr. Kathy Koch
In my current moment, the wise guidance offered in Dr. Kathy's latest book is a valuable gift.
Where many resources fail or miss the heart of things - the thoughts offered by Dr. Kathy in this book are practical, God honoring, honest, accessible, challenging, real.
It is common to find resources aimed at Jesus followers that land as impractical platitudes. It is common to find resources claiming psychological excellence that bury the reader in therapeutic blame shifting. This book is neither of those things and I am so grateful.
With a grown married child, an adult estranged child, an adult child still at home, a pre-launched teen, an aging parent, a frightening and sad loss of purpose in middle-age...I am the center of the target audience.
Each chapter brings focus to different areas of adult relationships that are prone to conflict. Each chapter ends with very useful tools to help focus on areas of healing and growth. The prompts for intentional, grace-filled communication are clear and immensely useful. There is compassionate seeing, firm challenge, and hopeful help. This book goes on my reference shelf for easy access!

What Do I Do When My DIL Wants to Cut Me Out of Her Life Along with My Granddaughter?
Format: Paperback, Format: Paperback
Answer to my question in my Review Title: I pray and God provided me this book! I just finished reading it, and I just couldn't wait to write this review! I highly recommending reading this book, if you are having any problems with your adult children, especially chapters 9-11. For me, like the title says, I didn't know what to do when my DIL said, "... I will be stepping back from contact for the foreseeable future. This includes cards, letters, gifts, or other communication unless I say otherwise." Since receiving that text message in December 2025, I have been praying about what to do. Just last week, my son texted me some very angry text messages, even demanding that I delete all virtual pictures of my granddaughter and giving him all my physical pictures of her (which I will do because of Matthew 5:38-42)! What amazing timing though to be reading this book! Praise God! My son has not closed the door yet on our relationship, so I have hope that I can implement some of the ideas in this book! See photo to see my notes (i.e. questions) that I wrote from the book that I could possibly ask him, if he is willing to meet with me. I pray that he does. Thank you SO much, Dr. Kathy, for writing this book! God is using you and your ministry. God bless you.
