I like everything that has to do with science from electronics to astronomy and from fossils to molecular biology. I also like very much history, politics and philosophy.
So as my current hobby is actually to read or watch documentaries for everything related with the above subjects.
My two real hobbies though is constructing electronic circuits like transmitters, amplifiers etc and making fireworks.
The last one is the hobby i always loved but unfortunately living in the center of Athens wasnt easy for this hobby. Keep in mind that with the politics of Greece those years and many terrorist attacks well it wasnt the most safe thing i could have for a hobby :) So after i ended up in the police department for a night i had to stop. I was quite lucky that this happened almost before Greece started going totally downwards...
