We've recently got back from Barcelona, where apart from playing a hockey tournament against the United States, Spain and Belgium, we had our own battle of Trivial Pursuit.

I was playing with team-mates Georgie Twigg and Susie Townsend on the iPad, switching off from hockey between games to earn pieces of pie. I made two full pies in a row, beating both girls, which didn't please one of them. "Twiggy", as she is known in the team, didn't get any points or answer any questions and ended up in such a strop that she just sat and stared out of the window.

When I'm not playing hockey I am a doctor at St George's Hospital in London, so law student Twiggy needed to be kept in her box about which of the professions is the more intellectual of the two. I'm glad the doctor managed to smash the lawyer on this occasion. All in good humour, of course.

While I am focusing on hockey in the lead-up to the Olympics I am working one day a week at the hospital. People sometimes ask whether I fall out of practice when it comes to work, but it's a bit like sport. When you gain experience, it is the familiarity with the patterns of work that become just as important as knowing every last little fact. But don't worry, I always make sure to take a little extra time to double check drug doses and things like that.

Having another focus is really positive for me and my hockey. When I've had times that I've not worked and only concentrated on hockey, I've actually ended up not playing as well. I find myself getting almost too intense and become too introspective, only focusing on the mistakes I'd made or what's not going well. So it's actually good for me to have something to take my mind off it, use my brain in a completely different way and be able to look at things differently.

Lots of people want to hear about the gunshot wounds that I operate on, but I actually find the human stories more interesting. I tend to remember those more than the gruesome stories which all merge into one after a while.

We are now coming into a big training phase for GB. We have been away so much over the winter, travelling to San Diego, Argentina and Spain but now we're back on UK soil for our final run in to the Olympics. Having played in 40˚C heat in Argentina, the cold here has been a bit of a shock to the system. As a goalkeeper I don't get to run around to keep warm like the other girls, so I end up freezing and wearing even more clothes.

I think the next few weeks will be really good for us. It's an opportunity to iron out some of the little details that we've highlighted over the winter.

We have our test event at the beginning of May, which will be our last competition before London. We've heard great reports coming from the other test events, like the gymnastics and swimming. They seem to really love their venues. So now we just can't wait to have our chance to test the Olympic hockey arena with its famous blue and pink pitch. We really are bursting to get out there. It's so exciting.
