Yeah, commoners have to fear the 10 foot fall, but...

But you would imagine the local butcher to have the highest mortality rate, until you consider the fact that rolling a 1 never does damage to you, so they never get cut on accident, lose fingers, get workmans comp. Also, there is no chance that a commoner will ever fall off a ladder, since rolling a 1 doesn't mean failure and succeeds at the ladder success DC. They can even climb a 500 foot knotted rope up a wall with no fear. Even if the ladder is slippery, there is only a 5% chance of falling. Man, what a life.
