Why do you suppose that those of us who spent many hours, days, and years 
cutting on the old black AO microtomes did not, and do not, seem to have the 
carpal tunnel syndrome that is so prevalent now?  Do some of you other "old 
timers" also agree with this.  I know that that sat much lower and were more 
comfortable to use than some of the newer microtomes, which require that you 
elevate your arms more.  That may be some food for thought in this for some 
of the current designers.
