A Quiet Advantage Of Being Left Handed

It took me about a month to realize something small but surprisingly important. being left handed is a quiet advantage if you are a teacher, a professor, or anyone who lectures using a board.

this becomes especially noticeable in fields that rely heavily on mathematical derivations or step by step written explanations.

I was attending a university lecture as a visitor. the lecture itself was already leaning toward boring, but something else kept bothering me. the lecturer was right handed. the more he wrote on the board, the more he erased his own work from the audience’s view, not with an eraser, but with his body.

Writing in English goes from left to right. a right handed person naturally starts on the left side of the board and moves right as they write. in a lecture hall with flat ground, this means the lecturer’s body keeps shifting rightward, slowly covering what was just written. students are forced to either wait, lean, or mentally reconstruct what they missed. it reminded me of a scanner passing over text, temporarily hiding it as it moves.

The contrast with left handed writing is striking.

A left handed lecturer writing left to right stands slightly to the right of the writing. the hand moves across the board while the body stays out of the way. the motion aligns naturally with visibility. the board remains open. the flow of information is uninterrupted.

it is a small physical detail, but in teaching, small frictions accumulate. losing sight of a formula halfway through derivation breaks concentration. clarity on the board directly affects clarity in the mind.

this realization stayed with me. if i ever become a lecturer, my students will not have to struggle to see what i just wrote. not because i am a better explainer, but because my body will not stand between them and the idea.

Sometimes advantages are not skills. sometimes they are about alignment. between motion and medium. between body and space.

being left handed, in this case, is a quiet gift.
