Success, however you judge what that even means, brings with it certain pressures.

I used to be mouthy. It was all to do with being a northerner and from Manchester, which was suddenly a big deal when I was in my 20s. When I read some of the interviews I did back then, I cringe.

Twitter has restored my faith in humanity. I thought I'd hate it, but while there are lots of knobheads, there are even more lovely people. It delights me how witty and friendly most people are.

I was good at being a doctor; my patients liked me. At times people trust you with things they wouldn't tell their spouses. It was a real privilege.

When the militias came to Wau, they would blast out 'Thriller' as they moved down the dirt streets.

I think to have the skill set and the ability to physically help others in matters of life and death must be incredibly empowering.
