It’s a perfect storm of protesters with heartfelt grievances and others set on conflict. The key here is the sense of betrayal that united them on the streets

The first thing I learned on the streets of Paris this weekend is that there is no arguing with teargas. I arrived at Place de la République just after 1pm yesterday. The mood was festive until police started firing volleys of teargas into the square from Rue du Faubourg-du-Temple.

I didn’t see the inciting incident – if there even was one – and tried walking into the cloud of CS gas hanging in the air. It was impossible. The gas clings to your nose and burns your eyes, and you quickly start struggling to breathe. I retreated towards the Boulevard de Magenta, blinking furiously to stop the stinging.

Meet some of the elderly residents of Bolotana, in line to be the world’s sixth ‘blue zone’ for its high number of female centenarians

When Giovanna Marras opens the door to her home in Bolotana, a mountain village in central Sardinia, her eyes are bright with curiosity as she sizes up her visitors. Her sister, Mariangela, peeks out too, soon ushering her guests inside and handing out dishes of ice-cream. The sisters are full of life, talking animatedly. Giovanna is 101 and Mariangela is 99.

Sitting in their living room, Giovanna swiftly recaps her life story: she excelled at school before moving to Cagliari, the capital of the Italian island, at 18 to train as a seamstress. The sisters went on to run a successful tailoring business in Bolotana before travelling the world after retirement. Neither married.
