My journey was supported by my many teachers and mentors who guided me to a world opened up by the enlightenment of higher education, and which led to my conviction that access to quality education is the social justice issue of our time.

Our business everyday is to make money for people. And I take it as seriously as doctors who are trying to cure cancer, because by giving people financial freedom, we allow them to do great things in their lives - from retire to send their kids to college, to buy their first house, to fund a business that they might want to start.

Well, it is of course a step-by-step process that started back in the 80s. I was struggling to retrieve a little bit of DNA from things that were just a few … starting with just dried tissues that, you know, that were just a few months old, going back in time and struggling with the technological issues with that over a decade. And then it became possible to retrieve DNA from things like the mammoths or cave bears that lived at a similar time as the Neanderthals. And then I was very lucky to get a job in Germany, where of course Neanderthals is a big presence in our, in the imagination of people, so it was then very, an obvious next step, in a way, to try to do that.

In Rakuten's case, adjustment certainly took time. At first, meetings often felt awkward. The first board meeting after the Englishization decision took four hours to complete – double the normal duration. But whenever executives asked if they could say certain things in Japanese, I told them no. I knew that the challenge would pay off – and it has.

One thing that I did was race against the British men a lot and they used to push me round the road; they used to make my life really hard but then when I was racing against the best women in the world, I'd been through just about every experience you could imagine. I remember this one race – a half marathon – where my husband literally pushed me into every kerb he could find, he pushed me into every corner, you know, messed around and tried to drop me out the back of the pack. Then when you're in a race that really matters, if that happens, you've got the skills to deal with it… you need to have practised everything you possibly could in the lead up to it.

I might have liked to have done it a couple of years later, but you'd be stupid to turn it down.

I love training. It's not just about the competing. I had an amount of natural talent – you need that to go so far – but, actually, what I had, I think, is an ability to make myself work hard, to do the things I didn't like doing, to do the things that I wasn't so good at.

We were training 12 to 15 times a week, 50 weeks of the year. I think sometimes people see you compete at the Paralympics or other amazing places around the world and think that is what you do all the time. There is an element of that, but a lot of it is just really boring and repetitive. The vast majority of your time as an athlete is spent on the road or in the gym.
