What is the last non-fiction book you read that changed how you think, feel or behave?

I'm looking for recommendations for what to listen to next and the bar has been set high by some incredible recent reads - please inspire me!

A book I think EVERYONE should read is 'With the End in Mind' by @drkathrynmannix

One of the most beautiful life (and death) affirming books I've ever read and has deeply informed my work on grief & bereavement

The audible narration is fantastic too: https://amzn.to/2GwPLm8 

I've just finished reading 'War Doctor' by @NottFoundation which charts David Nott's journey learning and teaching about surgery in times of war and devastation. It's humbling, inspiring and horrifying

Narrated by the author and so worth a listen: https://amzn.to/2SB2eaY
