In this episode we\u2019re taking a look at emergency medicine outside hospitals and surgeries \u2013 and meeting the people who save seriously-ill people in unusual places.

Smitha Mundasad goes on a rainy walk in the hills with the Brecon Mountain Rescue Team and meets the flying medics of London\u2019s Air Ambulance. Will she have time for a chat before they get a call-out? We also hear from Sweden where they\u2019re making lifesaving changes before the ambulance even arrives.

And from kombucha and kimchi to keffir and sourdough, fermented food and drink is everywhere. But as these foods have exploded in popularity, so have claims of health benefits, from digestion and gut health, to immunity and mood.

We start by trying some fermenting with chef Olia Hercules and then Smitha chats to fermented food \u201cnerd\u201d Professor Paul Cotter to sift through the evidence.

Next week\u2019s Inside Health is all about the perimenopause \u2013 the time leading up to the menopause when oestrogen starts to drop. Why is it all still such a mystery?

Send us your questions \u2013 and we\u2019ll put them to our panel. It\u2019s insidehealth@bbc.co.uk
