My favourite documentary, that’s lovely and everyone should watch, is called Water: The Great Mystery. It changed my perception of the whole planet more than maybe anything ever. Dr Masaru Emoto’s water research is very profound.

They wanted it for its artistic value. I found that deeply moving.

There are three. The documentary about Apocalypse Now that Francis Ford Coppola’s wife made is amazing. You should find it and watch it because Apocalypse Now, which is clearly more and more of a masterpiece every year and incredible because it’s still an unfinished work

I didn’t have a lot of mentors when I – I mean I kind of just grew up in the gym, just climbing a lot. So I didn’t really have mentors. I mean I definitely had people that I looked up to and people in the climbing community, but that’s just sort of the typical hero worship style, you know.
