I've been doing some reading about the proper workbench height. A lot
of sources say that for "general work" the proper height is right at the wrist
level of the user. Adjustments are made from there for specific types of
work.

If you were going to build a general purpose workbench for a new homeowner,
would you follow the wrist height rule? The person I have in mind is not a
woodworker. She knows which end of a screwdriver to use, but she might not
always use the right bit. ;-)
