I am a native slovak speaker, currently living in Prague. I understand Czech very well.
I use english for many years, too. It has been necessary for my scientific carreer as a plasma physicist. The same can be said about my PC skills.
During my free time I prefer to read psychology and self improovement books, practicing yoga and fitness. In the past I played ice hockey and floorball.
I am also a PC game fan.
Since I read many texts in english, I use to translate a lot.
