The Biology of Ageing
Ageing is identified as a process of degeneration rather than merely the passage of time. The podcast explains that as we age, our cells and tissues lose the ability to function optimally, leading to what are termed 'zombie cells' that refuse to die and accumulate in the body. These expressing cellular senescence contribute to the ageing process, affecting physical health significantly. By removing these dysfunctional cells, it is suggested that individuals can improve tissue, cellular, and organ function, thereby delaying the onset of age-associated diseases.
