I have known that from my school days. I reached my final size of 1.94 m a
 bit more that 76") at about 16 years of age and I always was the tallest in my
 classes (and during my military service).  Sometimes I succeeded in getting a
 higher desk than the others, but most like I did not and my mother had to go
to
 the teachers at least once a year: I could not sit straight as the teachers
 expected.

This continued all the way through the times when I was employed. We have a
 DIN standard that dictates a writing desk height of 72 cm (28"). Extremely
 comfortable desks may have a lift up to 74 or 75 cm (29"). My home-made desk
is
 78 cm (more that 30") high. My keybord is 69 cm (27") above ground and I am
 quite comfortable with the lower edges of my monitors some 95 cm (37") above
 ground.  This means that the upper edge of the 14" monitor of my BBS computer
is
 quite a bit below my eyes and upper edge the 17" screen is slightly below my
 eyes.

I can only agree.

In my opinion changing anything on a coworker's chair is quite impolite. I
 have seen people suffering for hours until they had settled down on new
 adjustments. But I change my working position quite often. I shift the
 keyboard around, put it on my knees (like at the moment) or do other
 variations. But you can do that with the keyboard only. At this moment I could
 not reach my mouse.

As a free-lancer working from my home I even have to change my working
 conditions more radically by doing some house work during the day or do my
 shopping. This freedom is one of the nicest things about my way of
 working.


Greetings from Germany,
Alexander
