With all of the people in Cuba who I met - many of them hugely heroic figures - I found learning about their complexity and richness and contradictions just really fascinating, and it was fulfilling to be able to offer a different side to them, to be able to have some kind of unique takeaway from the official narrative.

Hundreds of years ago, the most beautiful women of Havana were only glimpsed stepping in or out of carriages on this street. The first foreign writers who arrived and saw this could never get past just how incredibly beautiful their feet were.

Rigondeaux was Cuba's answer to Bobby Fischer who transformed into a kind of Lee Harvey Oswald traitorous creature in that society. He escaped on a smuggler's boat and toppled one of the best fighters in the world in 2013 with his obliteration of Nonito Donaire at Radio City Music Hall. He made it look so easy, his career has never recovered.

Is Duran's 'No Mas' a more defining moment in his career than his victory over Sugar Ray Leonard in their first fight? For many, it is.

Dealing with boys at work and being the only girl can be challenging. I have my insecurities, but I've learned I have to be a good sport. I have to be able to take certain jokes and not take them personally. There are jokes made almost every second of the day. I had to develop a tough hide. You know, the music industry is dominated by guys.

I only really watch sport. That's where you see real joy. I don't like watching much else on TV, because it's generally either twisted or sad.

Things have evolved, and footballers pay a lot more attention to how they dress and how they groom themselves because of social media. So they'll be on Instagram or Twitter, and I think it's one of those things - you're in the public eye more, probably, than playing football on television, and your lifestyle at home is broadcast.

Some boys accepted me, some didn't. And my family had comments made to them. Brazil is still a very macho society, and sports are mainly for boys, so people would say to them: 'What is this girl doing? Why is she always out there in the soccer games with the boys?'
