Nostalgia.
That's sentimental feeling you get when flicking through old photos or watching remakes of old TV series.
But can you feel nostalgic for something from before you were born?
I would be really interested to see what nostalgia will look like 20 years from now,
the now nostalgia of this era.
I'm Hannah Gelbart.
I'm the host of What in the World,
your podcast for the stories that get people talking from the BBC World Service.
Join me to hear how nostalgia affects the brain and what marketing has to do with it.
You can listen wherever you get your BBC podcasts.
Hello, welcome to the programme.
This is News Hour from the BBC World Service and it's coming to you live from London.
My name's Paul Henley.
First, trying to establish peace along the hotly disputed border between Thailand and Cambodia.
is proving a difficult stop-start process,
despite President Trump's claim that he personally sorted it out.
The latest ceasefire to have been established comes after pressure from China.
It freezes front lines and bans military reinforcements for at least 72 hours in a zone where fighting has driven more than a million people,
Cambodians and Thais, out of their homes.
