Left Foot, Right Foot

Lefties have it hard in a world that is made for righties. Starting in school, students encounter desks that are made for righties. There are one-piece desks where the student enters the desk on the left side and is able to use the right side for writing. There are ergonomic scissors that are a pleasure to use, assuming the user is a righty. Spiral notebooks and ring binders are generally made for righties. The spirals and rings will not get in the way of righties. Unfortunately, lefties will have to write awkwardly to use those products. Even kitchen gadgets such as can openers are often made for righties. In professional baseball, being a lefty is generally an advantage. That is unless the player is a catcher; there are no lefty catchers in Major League Baseball. (The reason for that is debatable) The good news is that this article can be read by either lefties or righties.
There is a related phenomenon to left-handedness, and that is left-footedness. Most people have a preferential foot. If someone needs to kick a ball or squash a bug, generally one particular foot will be preferred. Indeed, the Gemara bases one halacha of mezuzah on this fact. The mezuzah should be affixed to the right doorpost. The Gemara explains the reason for this halacha is that a person will reach the right doorpost first. Since most people are right-footed, they will enter a room by putting their right foot in the room first. Left-handedness and left-footedness do not go hand in hand or hand in foot. True, most left-handed people are, in fact, left-footed. Still, people can be left-footed and right-handed or vice versa.
