We’ve learned we’ve defied the passage of time from worms, fruit flies, and centenarians. Tom Perls met two persons who would impact his life in the early 1990s. Perls was visiting Boston’s HebrBoston’silitation Center for Ageing as a gerontology fellow at Harvard Medical School and needed to examine a couple of patients who happened to be over 100 years old. However, he was unable to locate them in their respective rooms. One patient, a 103-year-old woman, was eventually located.

Live to be Over 100 Years old

She was engrossed in her piano practice of Chopin and Mozart. Perls’ other Perls’t, a 101-year-old former tailor, was spotted fixing his housemates’ housemates in the occupational health unit. Perls, currently stationed at Boston University, says, “They really “startled me, and that’s when that ‘phony happened. “This person” appeared to be aging very slowly compared to others.” He vowed to”find as many more centenarians as possible to figure out their longevity secrets. The New England Centenarian Study, the world’s large world of very older adults, grew out of the effort.

Centenarians are no longer as uncommon as they once were. According to the Office for National Statistics, there were 15,120 centenarians in the UK in 2020 (almost double the number in 2002). However, receiving a birthday letter from the Queen is still a fantastic achievement. We spoke with longevity specialists about the science that could help us all get there and the aging myths you should know.

Myth: Aging has an evolutionary purpose

We need to understand why our bodies age in the first place before we can figure out how to slow (or even stop) it. However, Aston University biologist Cathy Slack claims that scientists are still undecided. “There’s no b”There’so aging from a purely theoretical standpoint,” she argues.

We used to think that aging was caused by a buildup of reactive oxygen species (free radicals) that caused molecular damage, but a new study indicates that this isn’t the casisn’tcording for Slack; the current most accepted view is that aging is an unintended consequence of biological mechanisms that encourage growth and reproduction in our youth.

The same systems that formerly made us fitter begin to make us sicker after a certain point, and the body cannot switch them off. The ‘hyperfunction” theory of aging is what scientists term it. “It’s like an “It’s that’s been that’s,” Slack adds.”You need to “fill the bath, but if you leave the tap running, the water will overflow, flooding your bathroom.”

Myth: As you” become older, your health will deteriorate

According to Perls ‘ research of centenarians, the musician and the tailor were not anomalies. People who live to be 100 years old are long-lived and escape significant illness until the end of their life. According to the medical histories of his participants, there are three types of centenarians. Around 43% are ‘delayers,’ meaning they’ don’t show don’t age until they’re in their ththey’reenties. Another 42 percent are ‘survivors,’ ‘ho are in ‘their 60s and 70s and have a chronic condition that does not kill them.

The remaining 15% are ‘escapers,’ people who are 100 years old or older and have no clinically detectable disease. True, age is a significant risk factor for various chronic ailments, including heart disease, dementia, and diabetes. Perls, on the other hand, feels that the old saying that “the older you” get, the sicker you get” is untrue. “e chooses to think of it this way: “The older you” grow, the healthier you’ve always you’ve.”

Myth: There”s nothiThere’scan to do to keep yourself from dying

According to Perls, centenarians, especially super-centenarians (those who live to be 110 years old), are likely to have genetic variations that protect them from age-related diseases. When it comes to lifespan, though, heredity isn’t the whoisn’tcture. Research reveals that genes account for only around 25% of the variation in human lifespan.

The majority of the money is spent on health-related behaviors and the environment. Perls point to California’s California’sAdventists as an example. This Christian denomination is up to a decade longer than the general population of California. It could be because they don’t smoke, don’t, or consume meat.

Perls believes most of us can live into our nineties if we start living a healthy lifestyle in our forties. Frank Hu, a nutritional epidemiologist at Harvard’s T.HHarvard’shool of Public Health, agrees. His study, published in the British Medical Journal in 2020, discovered five lifestyle characteristics that could give you an extra ten years.

People who never smoked, drank in moderation, had a healthy BMI, exercised for 30 minutes a day, and ate a high-quality diet increased their life expectancy, and the years they lived free of significant diseases, including diabetes, heart disease, and cancer. According to Hu, the findings give cause for optimism. “You don’t ha”e todon’tegan or run a marathon to be successful.” Small changes”s to your diet and lifestyle could help you live longer.

Stopping senescence may be crucial to living a long life.

Other research on longevity focuses on a type of cell that accumulates in our tissues as we age. These cells are no longer reproducing but also refusing to die. Biologists used to reject these zombies, known as senescent cells, as having little bearing on health or disease. However, some experts believe altering them could lead to healthier aging.

According to biochemist Judith Campisi of the Buck Institute for Research on Aging in California, senescent cells exude inflammatory substances that damage tissue and prevent surrounding cells from carrying out their regular functions. As a result, removing them from the body may help slow the aging process.

Mice administered senolytics, which selectively kill these senescent cells, lived longer than normal at James Kirkland’s reKirkland’sMayo Clinic in Minnesota and showed delayed onset of various age-related illnesses. Since then, several biotech companies, including Unity Biotechnology, have turned their attention to analytics as a potential fountain of youth.

However, not everyone is persuaded. Perls warns, “I don’t think” don’t goingthey’s a lot of people to 100.” analytics,” on the other hand, could be useful in preserving health in later age. He’s currentlHe’soking into senescent cells in his centenarians (and their relatives) to discover if individuals who age exceptionally well have a lesser load of cellular undead.

Fruit flies and Worms can Teach us a Lot.

Although research on extremely older adults is critical for understanding how to reverse aging in humans, we may also learn much about lifespan from seemingly unrelated animals like worms and insects. “When I tell “people I work with fruit flies, they’re usualthey’rerised,” Slack adds.” However, we “ow see that animals of very different species age similarly.

“Slack’s stud”Slack’s on insulin signaling and how it affects aging. “We know that”this signaling route permits the animal to grow larger and reproduce when it’s young,” it explains “ns. However, she’s discoveshe’shat blocking this mechanism causes the laboratory critters to live far longer than they should.

Slack claims she can extend the life of a fruit fly by up to 20% with no negative consequences other than the organism’s organism’s reproduction. Her research builds on a nearly 30-year-old discovery in which scientists deleted the insulin-signaling receptor from a worm and increased its lifetime by a factor of two. However, additional research is needed to see if these discoveries can be applied to humans and how you may change critical signaling networks without harming them.

Fasting could help you live longer

Scientists can use genetic editing tools to make flies and worms live longer, but they also know an easier way to extend the lifespan of organisms: hunger. Clive Mc Cay, a scientist, discovered in the 1930s that rats on highly restricted diets survived up to 33% longer than previously assumed.

More recent research from the Salk Institute in California compared rats on a standard diet with those who had eaten 30% fewer calories than normal since middle age. When the investigators looked at cells from various body regions, they discovered that cells from older dieting rats looked similar to those from relatively younger animals.

Such research suggests that calorie restriction in people could result in similar increases in lifespan and possibly other health consequences. For the most part, though, it is not an appealing or prudent endeavor. Intermittent fasting diets (such as the 5:2), in which people normally eat most of the time except for a few days on a low-calorie diet, are popular among dieters.

Some experts believe these approaches may help people live longer, but the proof is still lacking. “Intermittent” fasting is a terrific strategy for certain people to maintain a healthy weight,” Slack explains. “However, it “is to be seen whether it will be useful for living longer.”

Anti-aging “medications could be available soon

It would be much easier to take a drug to extend your life and, hopefully, your health. Some medications have been identified by scienScientists have identified some medications that appear to lengthen the lifespan of mice. Metformin, a diabetes medicine, also appears to help lab animals live longer.

Metformin has been linked to improved (unrelated) health outcomes, such as fewer heart attacks and cancer diagnoses, in human trials of persons taking the medicine for type 2 diabetes. In addition, a 2014 study found that diabetic individuals who took metformin lived longer on average than non-diabetic patients who did not take the medicine.

As a result of this hopeful research, there have been stories of people taking metformin off-label with the hopes of living longer. However, insufficient clinical proof exists that this drug would benefit healthy people. Researchers, on the other hand, are fascinated. The Targeting Aging with Metformin (TAME) experiment, conducted by Nir Barzilai at the Albert Einstein College of Medicine in New York, received FDA approval in 2019.

TAME will examine whether taking metformin increases how long someone can stay healthy (without stroke, heart failure, dementia, cancer, or death). “It’ll be fas”It’llng to see what happens,” Slack says.”Metformin is”really inexpensive. We must also remember that any medicine that helps people age well should be available to everyone.”
