How to Measure The Exact Age of Your Heart, According to Cardiologists
Various lifestyle factors can age your heart, while others help keep it young and healthy. For example, a 60-year-old who exercises and follows the Mediterranean diet could have the heart of a 40-year-old. Conversely, a sedentary 35-year-old who only eats ultra-processed foods may have a heart that's closer to 50.🩺SIGN UP for tips to stay healthy & fit with the top moves, clean eats, health trends & more delivered right to your inbox twice a week💊Not sure how old your heart is? Good news: You don't have to guess anymore. Scientists have identified an ingenious way to measure it, and it's so simple you can find out today—or at least this week. Related:
According to a recent study published in the journal Open Heart, getting an MRI (magnetic resonance imaging) can help identify the functional age of someone's heart. It can also reveal how certain unhealthy habits and health conditions age your heart by decades, the study authors said.For the study, doctors around the world collected MRI scans from 557 people: 191 were healthy and 366 had chronic health conditions such as high blood pressure, diabetes and/or obesity. The MRI type for the study used cardiac magnetic resonance and measured various factors, including the size and strength of the heart chambers. Using these measurements, the researchers applied a formula to estimate the heart's 'functional age." This refers to how old the heart acts, rather than a person's actual age.
'Our new MRI approach doesn't just count your birthdays. It measures how well your heart is holding up," explains , a cardiologist at the Norfolk and Norwich University Hospital and lead study author. 'This is a game-changer for keeping hearts healthier, longer."Related:
People who followed a healthy lifestyle had heart ages that closely matched their chronological age.
Meanwhile, those with chronic conditions such as diabetes, high blood pressure, obesity and/or irregular heartbeats tended to have hearts that aged faster than they did. For example, a 50-year-old with high blood pressure might have a heart functioning like that of a 55-year-old.
'Imagine finding out that your heart is 'older' than you are," says Dr. Garg. For people with conditions like high blood pressure, diabetes or obesity, this is often the case."That being said, a cardiac MRI scan is only one proposed method for measuring heart health. According to Dr. Cheng-Han Chen, MD, an interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center, who was not involved in the study, said there is, technically, no one universal "definition" of heart age."Much more research will be necessary before we know whether this particular method can provide clinically useful prognostic information," he explains. "We are still in the early stages of understanding how best to determine a 'heart age', and how such a calculation would help us better take care of patients."Related:
Heart disease is the leading cause of death for women in the United States, and it's also a top cause of death for men. Some people experience no symptoms until it's too late, discovering only after the fact that their hearts have already sustained serious damage.
Measuring your heart's age gives doctors a powerful tool to identify risk early and before it progresses into more dangerous or irreversible complications.
"People with health issues like diabetes or obesity often have hearts that are aging faster than they should, sometimes by decades," Dr. Garg explains. "This could help doctors step in early to stop heart disease in its tracks."
Dr. Chen adds other reliable methods for estimating your heart's age, including biomarkers like blood pressure, height and weight. Amassing such a detailed report of your heart might be the wake-up call people need to take their health seriously, before they enter their later years with a long list of preventable issues.Because at the end of the day, graceful aging starts from within.

The Growing Buzz Around Ancestral Wines
In the rolling hills of Valencia in Spain, winemaker Pablo Calatayud has joined forces with scientists and archaeologists to mount a small viticultural revolution—one that reaches back to pre-Roman times to recreate what have become known as ancestral wines. At his Celler del Roure, Calatayud is using large, egg-shaped clay amphorae to make wine pressed from grapes native to the region. The process is reconstructed from old texts and drawings carved into archaeological finds across the Mediterranean, including an ancient Iberian settlement that overlooks his own vineyard.

Feel Good Knees Introduces 'Knee Self-Restoration Ritual' Backed by Stanford Orthopedic Research on Natural Cartilage Healing
New York, Aug. 02, 2025 (GLOBE NEWSWIRE) — For decades, doctors claimed that cartilage couldn't heal itself. But recent studies—led in part by Dr. Constance Chu of Stanford University—are challenging that belief. Using MRI imaging, researchers have observed signs of natural knee joint regeneration, inspiring new approaches to non-invasive recovery. One such approach, featured in the Feel Good Knees system, is gaining traction among active adults and seniors looking to avoid surgery and reclaim pain-free movement. This 5-minute 'Knee Self-Restoration Ritual' is now being hailed as a gentle, science-guided method for unlocking the body's hidden healing potential. To see how this gentle routine is changing the way knee health is approached, visit the official Feel Good Knees Self-Healing System resource page. Why Interest in 'Knee Self-Healing' Is Surging in 2025 In 2025, more adults than ever are rethinking how they approach knee pain. A combination of rising surgery costs, drug-related risks, and breakthrough science is fueling public demand for safer, simpler alternatives that focus on the body's natural ability to heal. Searches for terms like 'natural knee pain relief,' 'cartilage regeneration,' and 'avoid knee surgery' have exploded on Google, while platforms like Reddit, TikTok, and YouTube are flooded with user-driven discussions around joint health, body alignment, and pain-free movement at any age. Why the sudden shift? For starters, many are becoming disillusioned with traditional solutions. NSAIDs—commonly used anti-inflammatory medications—are now under increasing scrutiny. According to the American Journal of Medicine, NSAIDs are linked to over 16,500 deaths each year from gastrointestinal bleeding, while countless others suffer from liver and kidney complications caused by prolonged use【Source: AJM; Singh 1998】. Surgical options aren't much better. The average knee replacement surgery in the U.S. costs between $30,000 and $50,000, and can leave patients with long recoveries, visible scarring, and recurring discomfort【Source: Healthline; 'What You Need to Know About Knee Surgery'】. And according to research published in Harvard Health , knee replacement implants often need to be replaced again after 10–15 years, creating additional surgeries and financial burdens down the line【Source: Harvard Health Publishing, 2023】. But perhaps the most exciting reason for this surge in interest is emerging from the scientific community itself. In a pivotal two-year study published in the Journal of the American Medical Association , researchers tracked 325 patients with knee cartilage degeneration. Using high-resolution MRI technology, they discovered that 37% of patients showed signs of cartilage healing—an outcome previously believed to be impossible. Their conclusion: 'MRI results showed cartilage repair and healing.'【Source: JAMA, 2023】 This finding was further echoed by Dr. Constance Chu, a renowned Stanford Orthopedic Surgeon and Professor, who has led research showing that articular cartilage possesses self-repair capacity under the right mechanical and biological conditions. Her stance directly contradicts decades of conventional wisdom that once damage occurs, it's permanent【Source: Stanford Medicine; Dr. Constance Chu Lab】. These data points, combined with mounting anecdotal success stories, have created a groundswell. People no longer want to merely 'manage' knee pain—they want to overcome it. And they're now open to exploring simple, non-invasive rituals that support their body's innate healing abilities. In short, the concept of 'knee self-healing' is no longer pseudoscience—it's a growing global movement, grounded in evidence, and propelled by everyday people who are ready to reclaim their mobility. Experience the difference a natural approach makes—explore the Feel Good Knees Self-Healing System now. Feel Good Knees as a Response to This Shift As millions seek non-invasive alternatives to injections and joint surgeries, one system is quietly leading the conversation: Feel Good Knees. This 5-minute-per-day method, known as the 'Knee Self-Restoration Ritual,' is designed to work with the body's natural recovery systems—without pills, painful physical therapy, or medical equipment. At the center of this approach is a simple question: what if the knees were never the problem, but rather the neglected victim of poor alignment, restricted mobility, and years of muscle imbalance? The Feel Good Knees system approaches joint discomfort not as a chronic curse, but as a correctable pattern—one that can be addressed with gentle, science-backed movement protocols. Developed by fitness educator and medical manual therapy specialist Todd Kuslikis, the program is built for aging adults who want to reclaim control of their mobility from the comfort of home. The system blends therapeutic isometric holds, alignment adjustments, and relaxation-based techniques designed specifically for sore, stiff, or post-surgical knees. No gym memberships. No risky devices. Just five minutes a day in a chair, on the bed, or even while standing. And its design wasn't random. Kuslikis created the program after watching his own wife suffer through knee pain so severe that it interrupted their daily lives—and even their intimacy. Armed with a background in kinesiology, calisthenics, and injury rehabilitation, he began assembling a toolkit of gentle, proven movements that support circulation, lubrication, and functional knee positioning. The result: a user-friendly program that doesn't require athleticism, prior experience, or even full mobility to get started. What makes it resonate so deeply with users is its simplicity. It doesn't promise to 'cure' anyone, nor does it rely on trends or gimmicks. Instead, Feel Good Knees positions itself as a natural response to a broken system—offering hope not through hype, but through self-guided action. In a market flooded with braces, pills, and quick fixes, Feel Good Knees stands out for its ability to restore not just mobility, but also confidence. It acknowledges the science of self-healing, incorporates modern orthopedic findings, and translates them into a ritual that real people can actually use. Ready to take control of your knee health?See how others are doing it with the Feel Good Knees program. What Online Users Are Saying About This Category Across the internet in 2025, a growing wave of users is challenging the mainstream narrative about joint pain—especially when it comes to aging knees. From Reddit threads and podcast transcripts to YouTube commentary and TikTok explainers, people of all ages are increasingly skeptical of the traditional 'pill or surgery' approach. What once felt like the default medical advice—NSAIDs, injections, or full joint replacements—is now facing resistance from everyday users who are openly sharing their frustrations and exploring non-invasive alternatives. On TikTok, videos tagged with #kneepainrelief, #naturalhealing, and #jointmobility now boast millions of views. Creators frequently talk about lifestyle upgrades, posture corrections, and overlooked alignment techniques that have helped them avoid surgery. Others share their experiments with mobility routines, barefoot training, or low-impact movement regimens—all seeking the same goal: pain-free movement without dependency. Meanwhile, popular podcasts in the health and aging space are dedicating entire episodes to mobility without medication, often highlighting overlooked therapies like isometric protocols, fascia release, and micro-adjustment exercises. Listeners are responding with enthusiasm, echoing sentiments like 'why didn't I hear about this 10 years ago?' and 'my doctor never told me there were alternatives.' In online review forums and comment sections, one theme is consistent: people want options that are gentle, proven, and accessible from home. There's a growing cultural belief that knees—like skin, muscles, and other tissues—shouldn't be excluded from the body's natural healing intelligence. The Feel Good Knees Self-Healing System has entered that conversation as a quiet frontrunner. While many systems rely on trends or unproven supplements, this method resonates because it taps into what online users already believe: that less can be more, and that a structured, low-resistance approach might actually work better than anything they've tried before. For many, it's not about avoiding doctors—it's about finally finding something that aligns with their values and actually fits into their daily lives. As one long-time wellness forum user put it, 'After all the braces, pills, and pricey gadgets, I can't believe a five-minute technique from a recliner is what finally gave me relief.' Learn why thousands are turning to this self-healing method—access the Feel Good Knees official guide. Who Might Gravitate Toward This Product in 2025 In 2025, the desire for pain-free movement isn't limited to athletes or injury recovery patients. It spans a much wider audience—people who are tired of feeling sidelined by discomfort and eager to regain control of their bodies, starting with their knees. The Feel Good Knees system was designed with these people in mind. Many are active adults in their 50s, 60s, or 70s who feel youthful at heart, but find their knees limiting their participation in everyday joys—whether it's gardening, golf, or chasing grandkids. These individuals aren't necessarily seeking high-performance results. What they want is freedom: the ability to move confidently, bend easily, and wake up without that familiar throb in their joints. Others include people who've had surgeries—some successfully, others not—who are looking for a way to support long-term joint health without relying on repeat procedures, follow-up injections, or prescription painkillers. Then there are those who've been proactive all along. Health-conscious individuals who believe in prevention and mobility longevity. For them, the Feel Good Knees ritual acts as a daily tune-up—gentle, grounded in physiology, and supportive of natural function. Even younger users, such as former athletes or those recovering from old sports injuries, are turning to this kind of program. Many are discovering that restoring patella alignment, relaxing overworked ligaments, and building low-impact joint strength can provide long-term comfort and stability—especially when done consistently over time. What unites them all is the mindset: people who aren't waiting around for pain to get worse. They want something simple, structured, and sustainable—without aggressive treatments or synthetic drugs. Whether you're just beginning to notice stiffness or have been managing knee discomfort for years, the Feel Good Knees system offers a calm, intelligent response to a complex problem. It doesn't demand hours of your time or access to a clinic. Instead, it gives you the tools to take charge of your recovery right from your recliner. To find out how this at-home system is helping thousands of people step back into life with strength and ease, explore the official Feel Good Knees Self-Healing System today. Market Category Reflections – Why This Niche Is Expanding The market for non-invasive pain management, particularly in the realm of joint support, has evolved rapidly in recent years. In 2025, a growing number of consumers are opting out of conventional solutions and exploring alternatives that were once considered fringe—such as fascia manipulation, isometric therapy, or passive alignment-based rituals. One of the fastest-growing subcategories within this movement is the self-guided, home-based mobility program. Products like Feel Good Knees are thriving not just because they're easier or less expensive—but because they're aligned with a deeper cultural shift. Today's consumers are more informed than ever. They question the idea that aging automatically leads to immobility. They research. They cross-reference clinical studies. They ask if surgery is truly the only option. And most importantly, they're demanding solutions that don't require them to surrender control of their bodies—or their wallets. This shift is reflected in keyword trends as well. Search volume for phrases like 'natural knee cartilage support,' 'home knee therapy,' and 'knee healing without surgery' has surged globally. Influencers and wellness practitioners are also fueling the conversation, contributing to what many now recognize as a full-scale category breakout. Part of this explosion in interest is due to the new wave of research validating the self-healing potential of joints. The 2023 JAMA study documenting 37% cartilage improvement in knees using natural, non-surgical methods has become a landmark reference point in online forums and health communities【Source: JAMA, 2023】. Additionally, Stanford University orthopedic professor Dr. Constance Chu continues to make headlines for her bold position that 'articular cartilage can heal' under proper conditions【Source: Stanford Medicine, 2023】. This single phrase, echoed across academic publications and interviews, has helped legitimize an entire category of non-invasive knee recovery methods that once existed outside the medical mainstream. But it's not just science driving the shift—it's demographics. The number of Americans over 60 continues to climb, and with it, a growing demand for mobility solutions that don't rely on narcotics, joint injections, or surgical implants. As the healthcare system becomes more expensive and overburdened, programs that teach users to restore function naturally—on their own terms—are being embraced as both a medical necessity and a personal empowerment tool. Feel Good Knees sits squarely in the center of that trend. It reflects the new definition of wellness: individualized, sustainable, evidence-informed, and low-risk. It also speaks to a larger consumer truth—people no longer want to be patients. They want to be participants in their own recovery. Take the first step toward pain-free knees—visit the Feel Good Knees Self-Healing System homepage. Public Debate – Supporters, Skeptics, and the Signals Behind the Buzz As interest in natural joint healing grows, so too does the conversation surrounding its legitimacy. The Feel Good Knees Self-Healing System has found itself at the center of this expanding debate—welcomed by many, questioned by others, and observed closely by professionals across fields ranging from physical therapy to biohacking. Supporters of the system point to the growing body of research that validates the potential for cartilage regeneration and biomechanical realignment, even in aging populations. They highlight studies like the 2023 publication in The Journal of the American Medical Association , which showed measurable MRI-documented cartilage improvements in over one-third of participants using non-surgical interventions【Source: JAMA, 2023】. They also cite expert commentary from Stanford Orthopedic Professor Dr. Constance Chu, whose work continues to affirm that knee cartilage may not be as static and unchangeable as once believed【Source: Stanford Medicine】. Beyond the academic world, practitioners in manual therapy and movement science have voiced support as well. They see routines like Feel Good Knees not as miracle cures, but as structured interventions that restore healthy joint mechanics through cumulative, low-impact input. In this light, the system becomes a tool for long-term maintenance, rather than a quick-fix remedy. However, not everyone is convinced. Skeptics warn that some users may overestimate the results or delay needed medical intervention. Critics argue that while natural healing is promising, it must be personalized and carefully monitored—particularly for those with advanced osteoarthritis, surgical complications, or degenerative meniscus damage. Others raise concerns about the oversimplification of knee biomechanics in popular marketing. They note that joint dysfunction is often multifactorial—impacted by weight, posture, injury history, and even genetics—and that no single solution, however well-designed, should be seen as universal. But even in these critiques, there is common ground. Most observers—supportive or skeptical—acknowledge that the system's emphasis on low-risk, low-impact routines is a net positive. The real disagreement lies not in whether such programs should exist, but in how broadly they should be recommended. What continues to tip the scale in the system's favor is one undeniable factor: user experience. With over 119,000 users and countless unsolicited testimonials reporting improved comfort, enhanced mobility, and a renewed sense of independence, the public momentum is difficult to ignore. Even many cautious observers admit that if a program is affordable, easy to follow, and doesn't interfere with conventional treatment, it may provide meaningful benefits—whether through physical stimulation or the psychological empowerment that comes with taking action. And that may be the most important signal behind the buzz: people want to participate in their own recovery. Not just passively treat symptoms—but actively work toward a better outcome. Uncover the breakthrough routine helping people move without pain—see what the Feel Good Knees System is all about.

‘Horny' mom, 42, reveals terrifying reason behind the sudden loss of her sex drive: ‘My partner took it personally'
A British mom says she was stunned to learn what was behind the sudden loss of her sex drive. Leanne Jones, 42, was once 'horny,' admitting she loved spending hours in the bedroom with partner Adam, 40. Several years ago, the former legal secretary suddenly found herself struggling to get aroused and wasn't able to climax as usual. 'I went from being very highly sex driven to feeling like Grandpa Joe from 'Willy Wonka,'' the mom-of-two, from South Wales in the United Kingdom, told Jam Press. 5 'I went from being very highly sex driven to feeling like Grandpa Joe from Willy Wonka,' the mom-of-two, from South Wales in the United Kingdom, told Jam Press. Jam Press/@leanne_fighting_ms 5 'There have been many times my partner could've walked away, but he says we are a team,' Jones said. She is pictured with Adam. Jam Press/@leanne_fighting_ms 'My partner took it personally at first, as many would, and thought I didn't love him anymore,' she continued. 'No matter how hard I tried, I couldn't get back my once horny self.' Jones was also experiencing 'crippling' fatigue and partial hearing loss. Knowing something wasn't quite right, she saw her doctor and was booked in for an MRI scan. Shockingly, the Brit was diagnosed with two conditions; Multiple Sclerosis (MS), which affects the brain and spinal cord, and functional neurological disorder, which impacts how the brain receives and sends information to the rest of the body. 'Because of the nerve damage to the brain and spine, the signals needed for arousal, sensation and orgasm are no longer there,' Jones explained. 'It creates a disconnect. For us women, there's issues with low sex drive, lack of sensation and lubrication and pain.' 5 'Because of the nerve damage to the brain and spine, the signals needed for arousal, sensation and orgasm are no longer there,' Jones explained.

Jam Press/@leanne_fighting_ms While Jones' partner was initially upset about lack of interest in sex, he is standing by her as she faces her health battle. 'There have been many times my partner could've walked away, but he says we are a team,' Jones stated.'I spoke with an MS neurologist in front of him about the issues we were having in the bedroom and he understood that it's not him, it's my brain.' Jones is now an advocate for other people who are suffering MS, taking to TikTok to explain how the illness impacts sex drive. 'I had a number of male sufferers message to thank me for discussing it as a few of them had lost partners over it,' the mom told Jam Press. 'This is why it's so important to raise awareness. It's such a debilitating and lonely life.' 5 In addition to her lack of sex drive, Jones is suffering from problems with her speech and issues with her mobility and vision. Jam Press/@leanne_fighting_ms In addition to her lack of sex drive, Jones is suffering from problems with her speech and issues with her mobility and vision. However, the mom insists she's still able to enjoy her life. 'I want people to know that even though it feels like a prison sentence, it's not,' she said. 'You've got to work with it, not against it, as there's so much to live for.'
