We begin by linking to an article that is interesting, but could have been even more interesting - and valuable - had they supplied some detail. The gist of the article, which is in Spanish (Google Translate does an adequate but not fantastic job with it), is that Levon Aronian's preparation for the Candidates includes work with the doctors and nutritionists of the Spanish soccer team Real Sociedad*. This is an excellent idea, and hopefully he started working with them soon enough for it to make a difference in the Candidates.

*Google Translate renders this "Royal Society" in English, giving the misleading impression that Aronian is working with the Spanish analogue to the British scientific society whose most famous past member was Isaac Newton. It's not; it's a soccer team.
