I am a retired university professor (Prof. Dr. Sc.) of nutrition. As a professor, I traveled a lot around the world. After retirement, following the trend of lifelong learning, I passed for a tour manager, as well as for tourist guide for City of Zagreb, Zagreb, Lika-Senj, Karlovac and Primorje-Gorski Kotar Counties for Croatian and English. As a professor at the university, I gained extensive experience in presenting and maintaining attention. Additionally, I also try to arouse curiosity and desire for new knowledge in the tourists I come in contact with.
