Mr. Saar lives in the south-east corner of Estonia, in the county of Vorumaa. Voru was the original language of Estonia, and is sometimes known as Southern-Estonian. What is today known as Estonian or the "Written-language" is a relative of Voru that diverged many years ago.

Mr. Saar has traveled extensively around the county of historical Vorumaa and documented the original names of all major geographical features there. In total, he has collected over 50,000 names from the Voru language.

Other famous Estonians have been known to call him for information about Estonian place names, even though he has no familiarity with the regions in question.

A busy farmer and father of a young girl, Mr. Saar also has a deep affection for Deep Purple, whose music was an underground hit during the Soviet period.
