Take some time for yourself with soothing classical music from the mindful mix, the Science of

Happiness Podcast.

For the last 20 years I've dedicated my career to exploring the science of living a happier more meaningful life and I want

to share that science with you.

And just one thing, deep calm with Michael Mosley.

I want to help you tap in to your hidden relaxation response system and open the door to that

calmer place within. Listen on BBC Sounds. This rock does seem very crumbly, look, it just crumbles in my hands so you could hear that breaking apart and there's a

bit of a landslide just literally over the corner does it happen a lot here?

Yeah it is it is a very dangerous place to stay below a war hagen cliff face.

Hello I'm Anan Jagatier.

This is crowd science and those are the sounds of me, my producer Louisa

and geologist Jesper Milan coming close to extinction on some cliffs in Denmark last year

when we travelled to Stairn's Clint to answer a question from listener Zareen in Bangladesh.

Could humanity go extinct like the dinosaurs? This week we are

revisiting the question of how the dinosaurs met their sticky end, but do not fear

if you have listened to the original program we're going to be covering plenty of new ground in this one.

In particular, we'll be answering some questions about potential doomsday scenarios for the human race.

Now, I can think of a few ways that humanity might

go extinct, perhaps a deadly disease pandemic might infect us all, or maybe

artificial intelligence will eventually turn on us with a vengeance, or possibly will suffer a

slow and steady death from the effects of climate change. But the apocalypse that's perhaps on everyone's

mind right now is a nuclear one.
