Day 250 : haberule


Sandy: Here is another bias left-handers claim not in their favor. Typically a ruler has markings with the zero on the far left and numbers incrementally increasing to the right. To mark a measurement, the right-hander would place the 0 at the starting point, hold down the ruler with the left hand and and make a mark or draw a line along the edge of the rule X inches away. If drawing with your left hand, you would hold the ruler with the right hand so when you draw a line, you reach across your right hand. I don’t think it is too much different for a right-hander who is reaching across the left hand in order to start at 0. In fact I think it is easier to see the stopping point when drawing with the left hand because the left hand doesn’t obscure the higher numbers on the ruler.

(The drawing is of my beloved Haberule which is obsolete. Used before computers could transform text into any size font with a few commands, this measuring tool was used by graphic designers and typesetters to spec type – calculate the length of text from a typewriter in order to fit it into a given space for printing).

Sandy’s year long journey – going from being a right-hander to left-hander, and Kelly’s parallel trip as a left-hander doing things as a right-hander.
