I usually like to learn the history about topics rather than the specifications or how do do it.
World history: I like to learn about foreign history. I am very biased towards Asia such as China, Japan, Korea, Iran and Turkey. The places outside of Asia that interest me the most are Mexico, Egypt, Italy and Spain.
Video games: I mainly like the games from the fifth and sixth generations (PS1 and PS2). I also really like Super Nintendo games. My favourite franchises are Street Fighter, Final Fantasy, Super Smash Bros., Metal Gear, Resident Evil and Tekken.
Following team sports: The Stanley Cup playoffs and the FIFA World Cup are my favourite tournaments. After that are the MLB, NFL and UEFA Champions League. I'm a casual NBA fan, I don't pay much attention during the season but follow it during the playoffs.
Professional wrestling: I really like WWE especially the time period between 1997-2003. When I feel like watching a good match though I sometimes watch NJPW or AJPW.
Movies: Action and horror. But definitely not an expert.
