"Rulers are used in education, working with paper, and other applications where you want confidence in a beginning mark. A rule has the beginning measurement at a well-ground edge with no initial measurement. "
May be that way because someone who spilled their hot McDonalds coffee in their lap had the ruler shown in the top of the image in their hand. The result was they then poked themself with the non-radiused corner. $100,000,000 later, the ruler company rounded the corners and offset the scale.
That lawsuit was the beginning of the end. The protection of idiots that would have been eliminated by natural selection.
Example: Closed course professional driver. Jumping a washed-out bridge could be hazardous to your health.
Sorry guys, yeah I was exaggerating to express what I felt was the ridiculousness of the legacy of that lawsuit(not the actual lawsuit). Seems to me that was kind of an inception point for what have become some pretty silly warning labels.
Maybe that person did deserve some compensation, but it just mushroomed into all these âcareful, eye injury may result if you run through a ice covered mine field with a pair of scissors pointed at your eyeâ type labels.
Weâre too civilized maybe. 150 years ago many of these folks would have been eaten by a bear or fallen off a cliff and not grown old enough to propagate their genes in the pool.
