Take a year off. I'm not going to give you any of that 'real world' garbage, but spending your whole life doing one thing makes for a dull person. Go learn to build a house or how to weld and you'll have something to fall back on if you get your PhD and can't find a job. And other people's comments about languages are absolutely true- chances are you'll have to gain a reading proficiency of a language you may not really need for your research. Unlike a lot of other people I encounter in academia, I think being multi-lingual is the mark of a true scholar, so I think having to learn these languages is a good idea. But it's still hard to get two languages down while doing a PhD, so taking a year off and getting a head start on languages while learning a trade is the right way to go.
