I feel you T_T or the fact right handed people can play WASD games more comfortably, with the mouse being on the right side of the keyboard. Can openers (the ones that you turn the handle). Kyudo (way of the bow) is only taught right handed. However it can be useful in that someone may not expect it; someone right handed used to fighting right handed people may not anticipate someone fighting left handed, thus getting caught off guard. But yeah I wouldn't change it, i like the uniqueness of it :D
