Young people seem to be moving away from Romania. In 2000, it had a population of 22.4 million people. But two decades later it had fallen to just 19.5 million - outward migration is responsible for most of that decline.

They’re mostly moving to other European countries, like the UK. Madeleine, from the What in the World team, went to a gig in London by a Romanian band called Subcarpați. While she was there, she chatted to young Romanian fans - why did they move away? And what does that mean for the country they’ve left behind?

It’s not just Romania that is seeing people move away for better work opportunities or to avoid a political climate they don’t like. Countries like Croatia have a similar situation - we hear from Baby Lasagna, a Croatian singer whose song ‘Rim Tim Tagi Dim’ is all about people leaving their home country.

Also, a dog called Bobi made news headlines last year when he was given the title of the world’s oldest dog by Guinness World Records. But some people don’t believe that he really made it to the ripe old age of 31. Whilst we don’t know yet if Bobi is going to lose his title (sadly he died not long after taking the crown) Alex from the team takes us through some other records that have turned out to be false. Including one very close to home…
