HOBBIES

I enjoy having fun when I'm not busy in the laboratory. I do swimming a lot, when I was at school I was swimming for the city team, although I'm not in a team anymore, I didn't give up this sport and swim regularly. Recently I have extended my water experience receiving PADI Open Water Diver certificate, so now diving is also my hobby, which I plan to upgrade (money and time allowing) to the Dive Master level. My other hobby is photography - you might wish to look at my gallery there are some decent photos. Photografy is also to be expanded to the underwater places, because there is so much interesting to see.

Apart from that, I often cycle during weekends to explore the neighbourhood or the cities nearby. Movies and good music also help to kill some time during rainy evenings. And I travel a lot. I like to explore different cultures and languages and meeting different kinds of people.
