The SENS framework
de Grey identifies 7 damage categories accumulating with age:
- Cellular loss and atrophy → stem-cell replenishment.
- Cancerous cells → WILT (Whole-body Interdiction of Lengthening Telomeres).
- Mitochondrial mutations → allotropic expression of mtDNA in the nucleus.
- Cellular senescence → senolytics.
- Extracellular crosslinks → AGE-breakers.
- Extracellular aggregates → amyloid-degrading approaches.
- Intracellular aggregates → lysosomal enhancement.
Influence
- Shifted longevity discourse from disease-by-disease to damage-decomposition thinking.
- Foundational to the SENS Research Foundation and Methuselah Foundation.
- Motivated senolytic development, though credit is shared with the Kirkland/Campisi laboratories.
Critique
- Timeline predictions have been consistently over-optimistic.
- Some SENS strategies (WILT, mtDNA allotropic expression) remain far from clinical.
- Others (senolytics) have moved from de Grey advocacy to mainstream biology.
Why it belongs on a longevity reading list
The most influential agenda-setting book of the modern longevity era — even where subsequent evidence has revised its specifics.
