I really like football and sometimes I bet on matches. Nowadays bookmakers offer a lot of markets, basically, you can bet on nearly anything from ‘Who will be the next president of the USA?’ to 'Which country is going to win the next Eurovision song contest?’ But sports events are still probably the most popular ones, especially football.
Two other things that I like are programming and predictions. I also have some background in math, statistics, and probability theory. Actually, it is more than a hobby I use them almost every day since I am a data scientist.
