Sarah Harte: Older women are reinventing themselves and defying ageism stereotypes

Sarah Jessica Parker is in the middle of a new act as a Booker Prize judge.
Back in Dublin for 48 hours, I bombed around the city using the Dart, on foot, and Uber. It struck me forcibly that there was a time when, with children reared, women receded unobtrusively into the background, their hair lopped off, wearing cosy cardigans and comfortable shoes.
Not the women I encountered in different settings over the weekend. These women were variously living with "zest and elan" in their second or third acts, trying on new identities.
