When the term “middle age” came into general use in the late 19th century, it was principally in a socio-economic setting. Empire and industrialisation had expanded and enriched the middle classes, and women who had finished raising children could enjoy another decade or two of vigour and relevance. Middle age was actually admired: these women were mature, worldly creatures who had, as the modern saying goes, “freedom to” as well as “freedom from”. The negative tarnish came with the mass production of the 1920s and the theories of scientific management that underpinned it, sharpening our association of youth with productivity and middle age with decreasing efficiency.
