Which theory of aging proposes that the body breaks down part by part after years of use Quizlet?

German biologist August Weismann introduced the wear-and-tear theory of aging in 1882. It is this theory of aging that proposes that the body breaks down part by part after years of use, suggesting that the body, much like a machine, slowly deteriorates over time due to continuous use and exposure to environmental stressors. While seemingly intuitive, this theory has faced significant scientific scrutiny and is now viewed as one piece of a much more complex puzzle regarding the aging process.

Is cell senescence good or bad? The complex truth behind 'zombie' cells

In the 1960s, researchers discovered that human cells have a limited number of divisions before entering a permanent state of growth arrest, a process now known as cellular senescence. Far from being a mere biological dead end, the question "Is cell senescence good or bad?" has become a central focus in the science of healthy aging.

How Does Altitude Affect Aging? The Dual Impact of Oxygen on Longevity

Recent research using advanced machine learning on facial photographs of Ethiopian highlanders found that while their life expectancy is higher, they also experience faster photoaging due to increased UV exposure. This surprising finding highlights the complex and dual-sided nature of how does altitude affect aging, presenting both pro- and anti-aging factors that depend heavily on elevation and individual genetics.
