“Elephants Don’t Get Cancer” is a very unique book.
It takes us across taxonomy, ecology, cytology, embryology, pathology, immunology, and microbiology.
"Oh my! How do you read this? You're absolutely right! It's not burdensome at all." _Lee Jeong-mo

Disease, emotions, intelligence, and social and cognitive abilities...
Solving a human puzzle that seemed like it would never be solved
How to survive on Earth, told by our most perfect neighbors, the 'animals'!

David B., who presented a new paradigm for health and created a sensation in the medical world with his New York Times bestseller, “The End of Illness.”
Agus is back with his latest hit, "Elephants Don't Get Cancer."
David B.
Agus is a world-renowned cancer authority and scientist who has received awards such as the American Cancer Society Research Physician Award, the Sloan-Kettering Institute Clinical Physician Award, and the International Myeloma Foundation Vision Science Award. He has dedicated his life to research to improve the quality of life for humanity.
This book explores human problems, which still have clear limitations, based on past research, and presents solutions through animals in nature.
'Why are giraffes, born with long necks, free from cardiovascular disease?', 'Why do ants let some of their comrades die and others live for perfect teamwork?', 'How do pigeons always win the Monty Hall Quiz that humans can't solve?', and 'Do elephants really not get cancer?', it talks about the physical and social systems that we can learn from them in a vast and systematic way, crossing over the fields of evolutionary biology, cytology, embryology, and microbiology.
You can experience the mysteries of life science through the operating principles of hormones, genes, DNA information, and the microbiome, which are important topics covered in this process.
From his days as a T-cell immunology researcher to his current position as a medical school professor and founder of a cancer treatment research institute, David B.
Anecdotes from the various people Agus met add depth and expertise to this book.

As life expectancy increases and we live to be 100 years old, the question of 'how to live this long life' has become important.
Discussions on health, such as slow aging, zero-sugar foods, and gut microbiomes, as well as on mental well-being, such as digital detox, positive psychology, mindset, and emotional intelligence, are occurring at an unprecedented pace.
In other words, this trend, which goes beyond the simple issue of longevity and is ultimately discussed as "well-aging," has become a representative desire and trend of society, and in that sense, "Elephants Don't Get Cancer" will be a timely book that will allow us to overcome the limitations of life and take a step forward.

Many animals do not get cancer or become obese.
They do not suffer from anxiety or depression, nor do they suffer from infectious diseases.
They do not show symptoms of cardiovascular disease or suffer from neurological disorders such as dementia or Parkinson's disease.
They don't get diabetes or autoimmune diseases, and they don't even develop superficial signs of aging like thinning gray hair, wrinkles, or arthritis in the knees.
Some creatures can hear without ears, see without eyes, retain their reproductive functions until death, regenerate lost limbs, revert to previous stages in their life cycle, communicate with one another without speaking or using anything resembling language, and think without having a brain.

Kent focuses his research on dogs, believing they are the best models for human health and aging.
Unlike rodents or other animals used in laboratories, dogs have complex physiology.
The disease process is also similar to ours.
This means that the way certain diseases manifest and progress is similar to that in humans.
Therefore, dogs are an excellent model for testing and studying the efficacy and toxicity of new treatments.
Dogs can develop cancer, diabetes, epilepsy, and canine cognitive impairments like Alzheimer's and Crohn's disease.
Moreover, they are often exposed to environmental pathogenic factors similar to those in humans.
We share more viruses with dogs than with any other animal, and dogs have immune systems that are remarkably similar to ours.

It is said that pigeons move their heads back and forth quickly to fix their eyes on an object momentarily so that the surrounding scene does not shake.
Sometimes, sit on a park bench and ponder this paradox.
Since movement naturally causes the field of vision to shake, all animals need a way to keep their surroundings still.
Without that method, your vision would become blurred and dizzy.
Human eyes are connected to the brain area that tracks movement and to the nerve muscles, so when there is movement, a slight eye twitching instinctively occurs, but pigeons use their long, flexible necks to track movement.
So, instead of actually shaking your neck, you lean your head forward, fixate your gaze on an object, and then your body follows that direction.

The cells of giant elephants rarely mutate, so the risk of developing cancer is very low compared to humans.
The chance that an elephant will develop cancer in its lifetime is less than 5 percent.
This means that less than 5 percent of all elephants die from cancer.
Scientists have known this for decades, since Richard Peto began his research in the 1970s, but only recently have they begun to crack the code for understanding the so-called elephant's anti-cancer profile.
Elephants have a robust anti-cancer system based on a protein called p53 (which has a molecular weight of 53 kilodaltons).
The anticancer molecule and the gene that encodes it, the tumor suppressor gene TP53, have received considerable attention over the past 30 years.
In particular, it has been receiving steady attention since 『Science』 declared it the ‘Molecule of the Year’ in December 1993.

Alzheimer's disease is a complex disease that cannot be explained by one thing.
Not everyone with this condition has problems with insulin regulation, and other hormones may also be involved.
Because Alzheimer's disease occurs overwhelmingly in women, recent studies are investigating how estrogen signaling may influence Alzheimer's risk.
However, since more than 80 percent of all Alzheimer's patients, both men and women, do not have a properly functioning insulin signaling system, insulin control is paramount.
Moreover, insulin signaling is important not only for preventing cognitive decline like Alzheimer's, but also for metabolism, which is responsible for many vital functions in our body from waistline to brain.
