Cellular Senescence
Zombie cells
Senescent cells are old, damaged cells that stop dividing but refuse to die. They accumulate with age and secrete inflammatory chemicals called SASP.
Why they're dangerous
Senescent cells make up a tiny fraction of your cells, but their SASP secretions poison neighboring healthy cells, spreading dysfunction like an infection throughout tissues.
Estimate the accumulation
By age 60, roughly what percentage of cells show signs of senescence?

Mouse studies are promising
When researchers cleared senescent cells in aged mice, the mice became younger — better fur, more energy, improved organ function, and 25% longer lifespan.
Key Takeaway
Senolytic drugs and fasting protocols are being studied to help clear these 'zombie cells' — one of the most exciting frontiers in longevity science.
