also.
in the past two days I have :

stacked 43400 boxes.
fed 33885 corregated sheets.

the sheets, yesterday / were fed at 9000 per hour.
the boxes, two days ago / were stacked at 15000 per hour.

I dont care for the math.
all in all, expect a more ... " nice " post when I have time to ...
... not be in pain.
