The Slovenian star of the book is basketball sensation Luka Dončić, who holds two records.

He is the teenager making the most triple-doubles in the NBA and the youngest player to score 30 points in a triple-double, having achieved this at the age of 19 years and 333 days.

Two Slovenians are also featured in the new section What happened on my birthday? in the international edition. Thirty years ago, Marija and Andrej Štremfelj became the first married couple to climb Mount Everest.

Back then Marija Štremfelj was only the third female European to climb the highest mountain, while she is still the only female Slovenian boasting this achievement.

Three more Slovenian records convinced the tough jury, which went through more than 100 applications every day before selecting the final 5,103 to be presented in the book.

Paragliders Bojan Gaberšek, Još Napret, Primož Suša and Dušan Orož made it into the book with their ten-hour return flight during which they overcame 302.1 kilometres.

The Rural Youth Association Škofja Loka managed to gather the most people in one place to manually cut grass. 564 of them gathered at Cerkno Ski Resort last August.

Slovenian Quidditch club Aemona Argonauts is also in the book for taking part in the Quidditch World Cup in Florence, where a record number of teams took part, 29.

The highlight of this year's issue of the book are the records in technology, especially in robotics, and environment, according to Mojca Benedičič, who is in charge of the Slovenian edition of the book.

The first Guinness Book of World Records was issued in 1995. Today it is published in 20 languages and has become the best-selling copyrighted book of all time. This year, the Slovenian version runs to 256 pages. It was released in 5,000 copies.
