'Body clock' could determine biological age and longevity, researchers say
Researchers have developed a new “body clock” tool that calculates people’s biological age — and could even predict the risk of disability or death.
The tool, which comes from the University of Washington (UW) School of Medicine, uses eight different metrics from a patient’s physical exam and bloodwork to determine the results, according to a press release from UW.
The tool’s method — officially named the Health Octo Tool — is detailed in the journal Nature Communication in a May 5 publication.
SECRETS OF LONGEVITY FROM THE WORLD’S ‘BLUE ZONES’
The researchers see this method as more comprehensive than current health assessments, which typically focus on individual diseases rather than overall wellness, according to the report’s first author, Dr. Shabnam Salimi, a physician-scientist and acting instructor in the Department of Anesthesiology & Pain Medicine at UW.

Using data from large longevity studies, the Health Octo Tool was found to predict disability, geriatric syndrome (a group of common health conditions in older adults), Short Physical Performance Battery (a clinical tool that assesses lower extremity function in older adults) and mortality with 90% accuracy or greater, the study reported.
“An aging-based framework offers a new path to discover biomarkers and therapeutics that target organ-specific or whole-body aging, rather than individual diseases,” Salimi said in the release.
HEALTHY EATING IN MIDDLE AGE HAS THIS KEY LONGEVITY BENEFIT
The tool focuses on “health entropy,” which encompasses the amount of molecular and cellular damage the body has sustained over time.
That has a direct impact on the function of a person’s organs and overall body systems, which can be used to determine how fast they are aging, the researchers noted.
“Aging is a truly analog and non-digital process.”
The tool starts by assigning a “body organ disease number,” ranging from 1 to 14, based on whether the patient has experienced any diseases affecting the heart, lungs, brain or other specific organ systems.
“Our findings demonstrated that organ systems age at different rates, prompting us to develop a Bodily System-Specific Age metric to reflect the aging rate of each organ system and the Bodily-Specific Clock to represent each organ system’s intrinsic biological age,” Salimi said.
LIFE EXPECTANCY IN HUMANS NOT LIKELY TO INCREASE MUCH MORE, STUDY SUGGESTS
“Extending this concept to the whole body, we define the Body Clock as a composite measure of overall intrinsic age and body age as the corresponding rate of aging.”
Two of the components of the tool, Speed-Body Clock and Speed-Body Age, measure how biological age affects walking speed.
“An aging-based framework offers a new path to discover biomarkers and therapeutics that target organ-specific or whole-body aging, rather than individual diseases,” said the lead researcher. (iStock)
The Disability-Body Clock and Disability-Body Age components measure aging’s impact on cognitive function and physical disability, the release stated.
One takeaway from the research was that some seemingly minor conditions, such as untreated hypertension early in life, could have a significant impact on aging in later years, according to Salimi. This indicates that treating these conditions sooner could slow down biological aging.
Looking ahead, the researchers plan to develop a digital app that people can use to track their own biological age, track how fast they are aging, and measure the impact of lifestyle changes.
“Whether someone is adopting a new diet, exercise routine or taking longevity-targeting drugs, they will be able to visualize how their body — and each organ system — is responding,” said Salimi.
“Aging is not a linear or wholly quantifiable process — it is influenced by myriad known and unknown genetic, molecular, environmental and psychosocial factors,” one doctor said. (iStock)
Dr. Brett Osborn, a Florida neurosurgeon who also runs a longevity practice, was not involved in the tool’s development, but commented on its potential benefits and limitations.
“This tool distinguishes itself by basing its model on readily accessible physical exam findings and standard lab tests, offering a potentially practical framework for clinical application,” he told Fox News Digital.
“An app is also being developed to empower patients and potentially encourage the development of health habits that will positively impact their healthspan — or how long they will remain functional and disease-free.”

The doctor also praised the Octo Tool’s focus on system-based aging metrics rather than disease-specific assessments.
Osborn noted, however, that there are limitations to these types of proposed biological aging clocks — primarily that they can’t counter the “inherent complexity of aging.”

“Aging is not a linear or wholly quantifiable process — it is influenced by myriad known and unknown genetic, molecular, environmental and psychosocial factors,” the doctor said.
“It is a truly ‘analog’ and ‘non–digital’ process. Therefore, it should be no surprise that no model has captured its entire landscape.”
The most important thing, according to one expert, is to use comprehensive testing and tracking as a springboard to the formation of lifelong health habits. (iStock)
UW’s tool doesn’t take into account certain genetic and DNA processes that influence biological aging, Osborn noted.
“Aging clocks have also often fallen short when applied across diverse populations or when predicting individual outcomes (lifespan),” he added.
“If it saves one person’s life by bringing their ailing health to their attention, that’s a win.”
Rather than determining absolute biological age, Osborn suggests using these tools to track trends over time.
“For example, tools like the Health Octo can help evaluate an individual’s response to interventions — be it a new exercise regimen, medication or lifestyle change.”
The most important thing, according to Osborn, is to use comprehensive testing and tracking as a springboard to the formation of lifelong health habits.

Colorectal cancer, once considered a disease of older age, is becoming a crisis for younger adults. New research shows one group getting hit the hardest – those without a college degree.
A recent study from the American Cancer Society analyzed data from over 101,000 adults aged 25 to 49 who died from colorectal cancer between 1994 and 2023.
While death rates remained stable for college graduates, they climbed significantly for those without a bachelor’s degree, the findings showed.
WIDESPREAD HABIT MAY RAISE COLORECTAL CANCER RISK MORE THAN YOU THINK
For young adults with a high school education or less, the mortality rate rose from 4.0 to 5.2 per 100,000 people, while the rate for those with at least a bachelor’s degree stayed flat, at approximately 2.7 per 100,000.
This does not mean that a degree offers some kind of biological protection, researchers cautioned.

The difference is likely driven by the conditions in which people live and work, which often correlate with education levels, the researchers noted.

The study suggests that the higher death rates are likely driven by differences in the prevalence of risk factors, including obesity, physical inactivity, smoking and diet, which are “known to be elevated among children and young adults with lower [socioeconomic status].”
Because the study relied on death certificates, researchers couldn’t say exactly why college graduates had better outcomes.
Because the researchers didn’t have the patients’ actual medical records, they couldn’t see things like frequency of screenings or treatment options, which would impact survival outcomes. (iStock)
Certificates typically list the cause of death, age, race and education level, but they do not include a person’s full medical history.

Colorectal cancer is now the leading cause of cancer death for men under 50 and the second leading cause for women in the same age group, according to recent statistics.
While colorectal cancer death rates remained stable for college graduates, they climbed significantly for those without a bachelor’s degree, the findings showed. (iStock)
Because the disease is highly treatable when caught early, the U.S. Preventive Services Task Force (USPSTF) lowered the recommended screening age from 50 to 45 in 2021.

A young woman who started vaping at the age of 15 has been given just 18 months to live — after being diagnosed with lung cancer in her early 20s.
Kayley Boda, 22, of Manchester, in the United Kingdom, was engaging in heavy vaping on a regular basis when she started coughing up a brown substance with “grainy bits” in it in January 2025, news agency SWNS reported.
The retail assistant said doctors turned her away eight times, telling her she had a chest infection — until she began coughing up blood.

After seven biopsies, Boda was diagnosed with lung cancer. She underwent surgery to remove the lower lobe of her right lung, as well as chemotherapy — and in February 2026, got the all-clear, the same source reported.
Two months later, though, doctors said the cancer had come back in the pleural lining. Now she’s been given 18 months to live.

The young woman has now issued a warning to others to be aware of the dangers of vaping.
Boda said she smoked a bit as a young teenager. She took up vaping after that.
Then, “a few months after I switched from reusable vapes to disposable ones, I started coughing up brown, grainy mucus,” as SWNS reported.

“Doctors turned me away eight times with a chest infection. … Then I started coughing up blood, so they did an X-ray and found a shadow on my lung,” she added.
“They told me they were 99% sure, [since I was] so young, that it wasn’t cancer, so not to worry about it. When I got the results back, and they told me it was lung cancer, it felt so surreal.”
Boda said she was “very naive” before her diagnosis and thought that “something like this would never happen to me.”
She said that she had surgery to remove half of her right lung.
“After the surgery, I started chemo and I had a terrible reaction to it. I couldn’t lift my head up. I was throwing up blood. I was urinating blood. I couldn’t eat. I couldn’t sleep.”

She said that when she got the “all clear [in Feb. 2026], it felt amazing, but just two months later I was told the cancer had come back, and I have 18 months to live.”
She added, “I’m 22. This isn’t meant to happen to somebody my age.”
“Stay off the vapes because they will catch up with you.”
She blames her cancer on vaping, she said.
“My symptoms started a few months after I started disposable vapes, and there’s no lung cancer in my family,” she said. “I haven’t vaped for three months, I’ve made my partner stop, I’ve made my mom stop, I’m urging all my friends to stop. Stay off the vapes,” she continued, “because they will catch up with you.”

She said she’d been using reusable vapes since the age of 15 and began using disposable vapes a few months before her cancer symptoms started.

In November 2024, when she developed a rash all over her body, doctors said it could have been due to shingles, chicken pox or scabies, she told SWNS.
‘Nothing worked’
“I got treated for all three, and nothing worked,” Boda said. “It got to the point where I was cutting myself from scratching so hard.”
A few months after that, she began coughing up a dark brown mucus, with “grainy bits, the consistency of sugar, in it,” she said. When the coughing continued, she visited the doctor’s office, but was told it could be scarring from pneumonia or a chest infection, she also said.

It wasn’t until March 2025 that she began coughing up bright red blood. At that point, doctors gave her a chest X-ray and told her they’d found a shadow on her lower right lung.
Over the next four months, she had seven biopsies as doctors took samples from the “shadow.” In August, when she went to get the results, she was told she had stage one lung cancer.

In September 2025, she had surgery to remove the lower lobe of her right lung, and the surrounding lymph nodes. During the surgery, doctors upstaged her cancer from stage one to stage three after finding cancer in six surrounding lymph nodes, she said.
Following the surgery, Boda was unable to breathe properly and had to learn to walk all over again.
“The oncologist said this is so rare.”
After finishing chemotherapy in February 2026, Kayley was given the all clear, leaving her feeling elated.

However, just a month after that, she began experiencing extreme chest pains and was told by doctors she had a pleural effusion — a build-up of fluid in the lungs. She had the fluid removed, but when doctors tested it, they discovered her cancer had returned to the pleural lining of her lungs, giving her 18 months to live.
“The oncologist said this is so rare, and usually something they see in patients that are 80 years old,” she said, as SWNS reported.

Boda claimed that doctors were unable to pin her cancer to a specific cause — but told her that smoking and vaping definitely didn’t help.
Since her diagnosis, she has stopped and is urging others to stop, too.

She’s hoping to raise the thousands of dollars needed for treatment to try to prolong her life, she said.
Last year, Fox News Digital reported on the case of a Pennsylvania woman, 26, who said she vaped for just one year before her lungs collapsed. She was 22 when she took up the habit, she said in an interview.
“Everybody warned me about it, but I didn’t listen — I wish that I did,” she said.

Dr. David Campbell, clinical director and program director at Recover Together Bend in Oregon, told Fox News Digital at that time that signs of collapsed lungs include sharp chest or shoulder pain, shortness of breath and difficulty breathing.
Lung issues are just one of the many health issues linked to vaping, he warned. The habit can also increase the risk of heart disease and stroke, as well as exposure to harmful heavy metals.

The key to feeling better in a fast, overstimulated world might be surprisingly simple: Live a little more like your grandparents.
A growing social media trend, dubbed “nonnamaxxing,” draws inspiration from the slower, more intentional rhythms associated with an Italian grandmother.
The lifestyle is often linked to activities like preparing home-cooked meals, spending time outdoors and making meaningful connections.

“Nonnamaxxing is a 2026 trend that embraces the slower, more intentional lifestyle of an Italian grandmother (a Nonna). Think cooking from scratch, long family meals, daily walks, gardening and less screen time,” Erin Palinski-Wade, a New Jersey-based registered dietitian, told Fox News Digital.

Stepping away from screens and toward real-world interaction can have measurable benefits, according to California-based psychotherapist Laurie Singer.
“We know that interacting with others in person, rather than spending time on screens, significantly improves mental health,” she told Fox News Digital, adding that social media often fuels comparison and lowers self-esteem.
LONELINESS MAY BE SILENTLY ERODING YOUR MEMORY, NEW RESEARCH REVEALS
Living more like previous generations isn’t purely driven by nostalgia. Cooking meals from scratch, for example, has been linked to better nutrition and more mindful eating patterns.
Adopting traditional mealtime habits can improve diet quality and support both physical and mental health, especially when meals are shared regularly with others, Palinski-Wade noted.
One longevity expert stresses that staying healthy isn’t just about food — it’s also about joy and community. (iStock)
There’s also a psychological benefit to slowing down and focusing on one task at a time. Anxiety often stems from unfinished or avoided tasks, Singer noted, and engaging in hands-on activities can counteract that.

“Nonnamaxxing encourages us to be present around a task, like gardening, baking or knitting, or just taking a mindful walk, that delivers something ‘real,’” she said.

Palinski-Wade cautions against turning the trend into another source of pressure, noting that a traditional “nonna” lifestyle often assumes a different pace of life.
The key, she said, is adapting the mindset, not replicating it perfectly.
