Disillusioned with the revolution after 68 years of US sanctions and a shattered economy, one in four Cubans have left in four years. Can the regime, and country, survive the engulfing ‘polycrisis’?

Hatri Echazabal Orta lives in Madrid, Spain. Maykel Fernández is in Charlotte, in the US, while Cristian Cuadra remains in Havana, Cuba – for now. All Cubans, all raised on revolutionary ideals and educated in good state-run schools, they have become disillusioned with the cherished national narrative that Cuba is a country of revolution and resistance. Facing a lack of political openness and poor economic prospects, each of them made the same decision: to leave.

They are not alone. After 68 years of partial sanctions and nearly 64 years of total economic embargo by the US, independent demographic studies suggest that Cuba is going through the world’s fastest population decline and is probably already below 8 million – a 25% drop in just four years, suggesting its population has shrunk by an average of about 820,000 people a year.

City targeted by Trump has seen swarm of immigration agents on the streets – and residents say the tension is palpable

Edwin Torres DeSantiago received a text message on Wednesday morning as he was tracking immigration enforcement across Minneapolis – a person was shot by ICE at 34th Street and Portland Avenue.

He jumped into his car to head to the scene. Torres DeSantiago manages the Immigrant Defense Network, a group that monitors ICE activity and responds to community needs after someone is taken. He has responded to dozens of scenes in the past few months, and even more in the last few days since the federal government surged its presence in the midwestern city.

There’s no bad time to take a more active interest in your health, but the new year, for lots of us, feels like a fresh start. Maybe you’re planning to sign up for a 10k or finally have a go at bouldering, eat a bit better or learn to swing a kettlebell. Maybe you want to keep up with your grandkids — or just be a little bit more physically prepared for whatever life throws at you.

They’ll be joining the Guardian’s Today in Focus presenter Annie Kelly to discuss simple, actionable ways to stay fit and healthy as you move through the second half of life: whether that means staying strong and mobile or stressing less and sleeping better.
