Hallo  Mr. Ellenberger,

You have asked for a description of my hobbies. Here it is.
The list would be: Computer, drawing, writing, walking, playing piano, creating jewelry,
supporting church music. (Maybe I forgot some hobbies which I am doing less often).

The most important hobby I have made my profession since 1996 is
programming of computers. And here first of all the application of medical knowledge.

A typical sort of „cross validation“ of Laboratory results is:
A patient serum has Measles-IgG positive and Measles-IgM negative;
my program writes a validation: Former measles infection or vaccination.
No sign of an acute infection.

Another example: 
The result is Chlamydia-IgG negative and Chlamydia-IgM positive+:
Suspect of acute Chlamydia infection if also Chlamydia-IgG goes up after control,
otherwise unspecific reaction. Occasionally cross-reaction with Chlamydia pneumoniae and psittaci.

Drawing:
Mostly I am doing it during holidays (not even every time). It makes me forget everything around.
During our holiday in Fuerteventura I made this drawing (pencil and ink.
I also like to combine cole and ink.
