20. It is difficult to understand what you really like if you only read about it or watch videos. You need to try and only then you will understand for sure. It was like that with downhill skiing - for the first 20 years of my life, I would not have thought that it was possible to have fun in winter. But I went to the mountains (fortunately, it was Grenoble) and from the first minute I realized what a thrill it was. But I found out about snow cleaning later. It's the same story with the "thirst" for travel: if you don't have enough for Dublin, go to Dubna, and don't open YouTube.
