Aubrey de Grey is a figure who does not remain invisible in the longevity field. In recent years, he founded the LEV Foundation (Longevity Escape Velocity Foundation), and he continues to be a voice that challenges assumptions. In a new interview from Longevity.Technology in 2026, de Grey presents a sharp perspective that frustrates researchers and excites his followers: Aging is not inevitable. It is a disease. And you can start treating it today.
Who is de Grey?
De Grey, a British biomedical engineer who studied at Cambridge, built his career on one concept: Aging is the accumulation of cellular damage, and damage can be repaired. He argued this in 2002, published his seminal book "Ending Aging" in 2007, and for 20 years has been one of the most prominent and controversial voices in the field.
The SENS Approach: 7 Categories of Damage
De Grey developed a framework called SENS (Strategies for Engineered Negligible Senescence). It divides aging into 7 categories of damage that can be treated:
- Cell loss: e.g., dying neurons. Solution: stem cells
- Zombie cells (senescent): Solution: senolytics
- Protein cross-links (extracellular cross-links): Stiffen skin and arteries. Solution: drugs that break them down
- Extracellular aggregates: like amyloid in Alzheimer's. Solution: antibodies
- Intracellular aggregates: like lipofuscin in the eyes. Solution: genes from bacteria that can break them down
- Mitochondrial mutations: Solution: "repair" genes that replicate mitochondrial genes
- Nuclear mutations (cancer): Solution: WILT (Whole-body Interdiction of Lengthening of Telomeres)
Five of these categories are already in clinical trials in 2026. Two are still research-stage.
The Key Insight: Longevity Escape Velocity
De Grey coined an important concept: "Longevity Escape Velocity". The idea:
"If science adds one year of healthspan for every year that passes, then once you reach the point where you are 80 and expect health until 100, you will live long enough to see the next treatment, and by the time that happens, the next one, and so on. Longevity could potentially become indefinite."
The calculation: For a 40-year-old today, there is a significant chance of reaching LEV. De Grey claims a 50% chance that a 40-year-old will not die from aging.
His Major Criticism: We Are Not Hurrying
De Grey is frustrated with the current pace of aging research. He argues that if society treated aging like COVID-19, we would have advanced LEV by 15-20 years. He calls for a "COVID-scale war against aging."
Topics Raised in the 2026 Interview
In his new interview with Longevity.Technology, de Grey discusses several updated topics:
Intrinsic Capacity
A WHO framework that measures physical, cognitive, psychological, and sensory function in the elderly. De Grey supports the approach because it allows early detection of decline and early intervention. "It plays the role of a 'blood pressure test' but for the whole body".
GLP-1 Drugs as Prevention
De Grey sees huge potential in Ozempic and similar drugs. "Not because we want everyone to be thin, but because chronic cellular inflammation, which they reduce, is one of the main obstacles in aging". He predicts that within 5 years, GLP-1s will be considered basic rejuvenation drugs.
Longevity Clinics
De Grey supports the idea of "longevity clinics" offering tests and treatments for longevity. But he emphasizes: most existing clinics are "half-marketing, half-science". The public should be cautious.
ARPA-H and Funding Limitations
He is critical of ARPA-H (a new US research arm to accelerate medical innovations): "It was created for 'targeted solutions' but doesn't think broadly enough. Longevity requires 100 times more funding than what exists".
His Practical Recommendations
Why you shouldn't wait, according to de Grey:
- Don't wait for a miracle drug. Use what's available: senolytics in clinical research, GLP-1 in appropriate cases, metformin off-label if your doctor agrees
- Low-calorie diet + solid supplements: Vitamin D, Omega-3, NAD+
- Regular intense physical activity: A combination of cardio and strength
- Sleep is the cheapest and has the greatest impact
- Routine biomarker tracking: At least once a year
- If you have the capital and leisure: Consider participating in clinical trials. It helps research and also helps you
Criticism of de Grey
It is important to note that the scientific community treats de Grey with great caution. Common criticisms:
- Overly optimistic predictions that don't always materialize on his timelines
- The SENS framework is based on assumptions that are not all proven
- His presentation style is sometimes more promotional than scientific
But even critics admit: de Grey succeeded in changing the conversation. A field once considered "science fiction" is now serious research with billions of dollars in investment.
The Bottom Line
If de Grey is only half right, we are facing a dramatic change in human life. If he is completely wrong, even then the interventions he recommends are healthy. The risk is low, the potential is huge. His recommendation is simple: Don't wait for the future. Start treating aging today.
