I think the last line is interesting "They’re defying the expectations of cute and dignified little old ladies." Older women are often seen as cute little old ladies, the reality issue many are often are working incredibly hard providing unpaid care to grandchildren and ageing partners, many in this age group also form the core of community volunteer groups. The idea that older women "cute" but irrelevant hides the essential labour they do in our society. It's sad to me that older women need to be 'sexy' to be seen, rather than being valued for the important contribution they make.
