If I were to indeed qualify this “life's achievement-co-achievement” volume as the full stop at the end of my professional career, then the year 2022 could be inserted into the above parenthesis. One of the most important lessons I learned during my long career is: never say never. Thus, only the initial year remains within the parenthesis. The more so, as possibly the 2022 edition of the Hungarian original of this book can be “blamed” for the very honoring invitation to join the Faculty of Water Sciences of the Ludovika University of Public Service as research professor.
