Compared with people who reported drinking no coffee, those reporting 3-4 cups per day had longer telomeres, while those reporting 5 or more cups per day did not show the same association.

These findings reposition the thymus as a central regulator of immune‑ mediated aging and disease susceptibility in adulthood.

The AI analysis found enormous variation in the health of the thymus between individual people. In some people, it stayed very active until a very old age. And other people, it actually declined very rapidly at a younger age. Importantly, thymus health correlated with a person's overall health. People who had a healthy thymus tended to live longer, have less cancer, and less cardiovascular disease.

As we age, several things happen simultaneously in our skin. Antioxidant defenses in the skin decline, the composition of our sebum changes, and our cumulative UV exposure and environmental stress increase oxidative damage in the skin. As these things are weakening the skin, 2-nonenal has an opportunity to make its presence known.

The Israeli gerontologist has been studying healthy centenarians for years and has observed that many follow a pattern similar to Reichert's. They do not always lead a monastic, carefully balanced life. There is a great deal of biological lottery involved in longevity. But Barzilai wants to hack that lottery—to understand which numbers are the winning ones and pass them on to the rest of humanity.

It got me thinking. While everyone's obsessing over the latest fitness trends and biohacking protocols, these folks have been consistently moving their bodies for decades. No fancy equipment, no Instagram-worthy routines, just simple habits they picked up long before movement became a multibillion-dollar industry. So I started asking around, digging into research, and talking to people who've stayed active well into their golden years. What I found wasn't revolutionary or complicated. It was refreshingly simple.

As you age, your body gets less efficient at repair and recovery, as your: Immune system gradually loses some of its resilience Digestion slows Chances of chronic conditions like heart disease, type 2 diabetes, and osteoporosis increase Retirement can also impact your health in complex ways. While stepping away from work often reduces stress, it may lead to less physical activity and fewer social interactions-both of which can raise your health risks.

Researchers administered one of four doses of stem cells to 118 people between 70 and 85 years old, all of whom had frailty. In a timed walking test nine months after treatment, those who had received the highest dose could walk about 60 metres farther, on average, than they could before treatment.

US researchers found that engaging in intellectually stimulating activities throughout life, such as reading, writing or learning a new language, was associated with a lower risk of Alzheimer's disease, the most common form of dementia, and slower cognitive decline. The study author Andrea Zammit, of Rush University Medical Center in Chicago, said the discovery suggested cognitive health in later life was strongly influenced by lifelong exposure to intellectually stimulating environments.

"As we get older, the immune system is shifting away from good inflammation," which is the body's short-term, acute response to fend off injury or infection and promote healing, explains Dr. Thomas Marron, one of the researchers leading the new study. Marron directs early phase clinical trials at The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai.

Researchers used data from two health studies to track the caffeine-drinking habits of more than 130,000 people over four decades. They found that drinking 2-3 cups of coffee or 1-2 cups of tea a day was associated with the greatest reductions in rate of cognitive decline, a result that held true even in people with a genetic variant called APOE4, which is associated with Alzheimer's disease.

A groundbreaking study found that adults who sit for 10 or more hours daily face a significantly higher risk of dementia compared to those who sit less. The research, which tracked over 50,000 adults using wearable devices, revealed that the risk increases dramatically after crossing that 10-hour threshold.
