During my studying on secondary school I didn’t do any active sports and I watch sport on TV only. I did only some sport recreative for example cycling and swimming. When I began to study at university I missed some sport. After I graduated then I started to study PhD program I found out that sport is very important part of my life. Sport gives me not only pleasure but also relaxing from mental work at university. My favorite sport is cycling especially on mountains and I did it with my friends during holidays. I have to mention swimming too because I love swimming. My another different hobby is computers. It is maybe my biggest hobby. I am interested in computers for a long time from my 15 years old, when I gave my first personal computer.
