Ageing
The foam used in buoyancy aids does degrade with age. Manufacturers add additional foam to ensure that their buoyancy aids will still provide enough force even after years of use. A rough life expectancy is three years of use, although buoyancy aids exposed to polluted water may degrade faster than normally expected.

Famous quotes containing the word ageing:
“Our civilization survives in the complacency of cowardly or malignant minds—a sacrifice to the vanity of ageing adolescents.... In 1953, excess is always a comfort, and sometimes a career.”
—Albert Camus (1913–1960)
“But I must needs take my petulance, contrasting it with my accustomed morning hopefulness, as a sign of the ageing of appetite, of a decay in the very capacity of enjoyment. We need some imaginative stimulus, some not impossible ideal which may shape vague hope, and transform it into effective desire, to carry us year after year, without disgust, through the routine- work which is so large a part of life.”
—Walter Pater (1839–1894)
