Cutting-edge research in geroscience is pushing the boundaries of human longevity, raising the tantalizing question: could someone someday celebrate a 150th birthday? Leading scientists are betting yes, and the focus has shifted from simply treating individual diseases to targeting ageing itself—the underlying risk factor for most chronic conditions like cancer, heart disease, and dementia. Over the past century, conventional medicine dramatically increased average lifespans, but further gains have stalled. Experts now agree: slowing the biological process of ageing, rather than pursuing isolated disease cures, is the key to meaningful healthspan extension.
Strategies under investigation include studying centenarians for clues to natural resilience, exploring calorie restriction’s effect on lifespan, and boosting sirtuin activity—genes linked to cellular repair—by increasing NAD+ levels. Early trials show NAD+ supplements may lower disease-related inflammation in humans, with promising, but not yet proven, effects on longevity. Another focus is “inflammageing”—the chronic inflammation driving age-related decline. Scientists are testing IL-11 inhibitors, based on findings that blocking this cytokine extended lifespan in animal models; major clinical trials are underway to confirm effectiveness in people.
Other anti-ageing approaches include clearing senescent cells with drugs called senolytics, though their benefits haven’t yet translated in human studies. Repurposing medications such as metformin and rapamycin is also being explored—these drugs can mimic metabolic pathways triggered by calorie restriction, with rapamycin showing promising results in animal studies. The central theme: improving not just how long we live, but how well. If successful, these interventions could usher in a new era—one defined not by longer life alone, but by decades more lived in robust health.
