Aging is ultimately a combination of physiological changes in our bodies and the environmental factors we are exposed to.

The accumulation of senescent cells is the hallmark of cellular aging, which in turn translates to biological aging. 1 . The more damage done to cells by free radicals and environmental factors, the more cells need to replicate and the more rapidly that cellular senescence develops. 1 . The Telomere Theory of Aging.
What is accumulative damage?
Accumulative Damage. Aging caused by accumulative damage (i.e., "wear and tear") is about the external factors that can build up over time. Exposure to toxins, UV radiation, unhealthy foods, and pollution can just some of the things that can take a toll on the body. 4 .

When did we start relying on chronological age?

Starting around 200 years ago , governments began to accurately record birth dates and then started to use chronological age to segregate society. Schooling became defined by age cohorts.
When was the retirement age established?
The apotheosis of this approach was the creation of a “ retirement age ,” broadly defined as 70 in 1908 and then as 65 in 1925. In response, individuals began to base their sense of age on their birth dates. Today, we think about age in terms of the number of candles needed for a birthday cake.
