Imagine living to 150, looking decades younger, and feeling vibrant well into old age. It sounds like science fiction, but leading longevity scientists believe it’s within reach. They’re not just theorizing—they’re testing drugs, supplements, and lifestyle changes on themselves, offering a glimpse into a future where aging is no longer an inevitable decline. But here’s where it gets controversial: some of these strategies are already available, yet most people have no idea they exist. And this is the part most people miss: it’s not just about living longer—it’s about living healthier longer, free from the diseases that often come with age.
The field of geroscience is revolutionizing our understanding of aging. Scientists are targeting the root cause of nearly every major illness: cellular damage and chronic inflammation. As we age, our cells accumulate damage, and our bodies become less efficient at repairing themselves. This leads to a cascade of problems, from cancer and dementia to heart disease. But what if we could slow—or even reverse—this process?
One groundbreaking development comes from biotech company Mabwell, which is testing a drug that blocks interleukin-11 (IL-11), a molecule that spikes as we age. In younger people, IL-11 levels rise temporarily during illness, but in older adults, immune cells produce it constantly, leading to chronic inflammation that damages organs like the heart and lungs. A 2024 study in Nature found that blocking IL-11 extended the lifespan of aging mice by about 25% and reduced the severity of age-related cancers. This has caught the attention of Calico Life Sciences, a Google-backed company focused on anti-aging therapies, which recently secured an exclusive licensing deal for the drug.
But IL-11 blockers are just the tip of the iceberg. Drugs like semaglutide (Ozempic, Wegovy), originally developed for diabetes and weight loss, are showing promise in slowing age-related diseases. A 2023 study in The New England Journal of Medicine found that semaglutide reduced heart attacks and strokes by 20% in people with obesity and cardiovascular disease. Even more intriguing, only a third of this benefit came from weight loss, suggesting the drug has additional protective effects, such as reducing inflammation. It’s also been linked to a lower risk of Alzheimer’s.
Here’s where opinions start to diverge: some scientists, like Professor Stephen Austad of the University of Alabama, are so confident in these advances that they believe the first person to reach 150 is already alive. Others are more cautious, noting that it could be years before these drugs are widely prescribed for longevity. But what are the experts themselves doing to extend their healthy years?
Take Matt Kaeberlein, a professor of biology at the University of Washington and founder of a ‘healthspan medicine’ company. He takes evolocumab (Repatha) to lower cholesterol, empagliflozin (a diabetes drug) to improve insulin sensitivity, and a tiny daily dose of lithium orotate—a mineral linked to lower dementia rates in regions with high lithium in drinking water. He also takes rapamycin, a drug originally designed to prevent organ transplant rejection, which has shown remarkable anti-aging effects in animals. But rapamycin is controversial: while it’s been shown to boost immune function and reduce inflammation, its long-term effects in humans are still unclear. Biohacker Bryan Johnson, for example, reportedly stopped taking it due to side effects, though Kaeberlein notes that Johnson’s regimen of 100+ supplements makes it impossible to pinpoint the cause of any issues.
Not all experts are on board with experimental drugs. Professor Nir Barzilai of the Albert Einstein College of Medicine focuses on lifestyle changes, like daily exercise and fasting (eating only between noon and 8 PM). He also takes metformin, a diabetes drug that’s being studied for its anti-aging effects, and emphasizes the importance of genetics. ‘Fifty percent of men who live to 100 and 30% of women are smokers,’ he points out. ‘Their genes protect them from aging.’ But even if you didn’t win the genetic lottery, Barzilai believes you can still influence your biology through exercise, diet, and proactive healthcare.
Professor Andrea Maier of the National University of Singapore takes a data-driven approach, advocating for ‘gerodiagnostics’—regular tests to measure biomarkers like blood sugar, cholesterol, and epigenetic age. She focuses on gut health, strength training, and ‘dual-task’ training (combining movement with mental tasks), which has been shown to improve cognitive function and reduce falls in older adults. ‘Strength training is the most underrated gerotherapeutic,’ she says.
So, what’s the bottom line? While there’s no magic pill for longevity, the experts agree that a combination of lifestyle changes and targeted interventions can add 10-15 healthy years to your life. But here’s the thought-provoking question: are you willing to experiment with drugs like rapamycin or metformin, or do you prefer to stick to proven strategies like exercise and diet? And if these therapies become widely available, who should have access? The debate is just beginning, and your voice matters. Share your thoughts in the comments—let’s start a conversation about the future of aging.
