What is the damage or error theory of aging?

According to research published by the National Institutes of Health, modern biological theories of aging are broadly categorized into two groups: programmed theories and damage or error theories. This article explains what is the damage or error theory of aging, an idea that posits aging results from the accumulation of damage to cells and tissues over time due to both internal metabolic processes and external environmental factors.

Which theory of aging states that unstable oxygen molecules cause damage?

Every human cell is engaged in a constant chemical battle, a phenomenon highlighted by one of the most prominent theories of aging. The Free Radical Theory of Aging states that unstable oxygen molecules, known as free radicals, inflict cumulative damage upon cells over a lifetime, leading to the physiological changes associated with growing older.

What Is the Cellular Theory of Aging? Exploring the Body's Biological Clock

In 1961, Leonard Hayflick and Paul Moorhead observed that human cells have a limited capacity to divide before they stop replicating, a concept known as the Hayflick limit. This discovery underpins the **cellular theory of aging**, which posits that the body's aging process is driven by intrinsic changes within our cells.

Understanding the Silent Shifts: What type of cells are found increasingly between the gland tissue with increasing age?

As we age, our bodies undergo silent, microscopic transformations that influence our overall health. Glandular tissues, vital for producing hormones and other substances, are not immune to these changes. A key question in cellular aging research is **what type of cells are found increasingly between the gland tissue with increasing age**, a phenomenon that provides insight into declining organ function and the progression of many age-related conditions.
