Computer
This is my favorite hobby (surprise, surprise). Since I grew up in the early days of the Computer and allways had a affiliation to electronics and machinery there is some sort of intuitive touch between me and the computer I am working with.
Question: How did we manage our work/live without Computer?

S.K.V.-P.S.K.-Kegelsektion
No this is not the game with the ten "Kegeln", but the one with the nine!
(The other one is called Bowling and to say it the right way there are: "Pins")
If someone wants to watch us playing - mainly we play in the B.K.V. (=Betriebs Kegler Vereinigung that is the Union of Kegler of Businesses in Vienna) and second in the Bank-League.

Reading
If there is some time in between, I love to read as much as I can.
Especially engineering-magazines are a part of business- and hobby-like continuation of my education; for relaxation it may be a Science Fiction- or other Action-novel.
Most of all I like to read books to movies that i have first seen in the cinema.

Going to the cinema
Well, besides all the former listed actions and the business-necessity there is only very little to no more time left for this hobby :-(
