They break down key drivers - or “hallmarks” - of aging, including mitochondrial dysfunction, stem cell exhaustion, and declining communication between cells, and explain how these changes can affect energy, inflammation, and the body’s ability to repair itself. They also explore practical strategies including exercise, cold exposure, and molecules such as berberine, curcumin, metformin, and resveratrol, alongside emerging research into mitochondrial replacement and stem cells.
