Ageing Versus Disease: Biological Boundaries

Dr Shara Cohen

What is the difference between normal ageing and disease? This article explores the biological mechanisms that separate healthy ageing from pathology, including cellular decline, inflammation, and disease risk.

What Ageing Actually Is: Biological Change Across the Lifespan

Dr Shara Cohen

Ageing is a lifelong biological process. This article explains how the body changes from early development to later life, and why ageing is not the same as disease.

Understanding Ageing

An evidence-based platform dedicated to explaining how and why the body and mind change over time, separating normal biological ageing from disease. The site translates complex scientific research into clear, practical guidance, helping readers understand what is typical, what may require medical attention, and how lifestyle, environment, and genetics interact across the lifespan. With a focus on clarity, credibility, and proportion, it provides structured articles, expert insights, and accessible explanations designed to support informed decision-making rather than fear, stigma, or oversimplification about growing older..
