A quick question: following prompts, trying to remember forms and movements, how crucial is left and right? I mean that not only am I left-handed, I'm extremely left-sided: my left eye is slightly myopic, my right very much so; my left shoe wears out much quicker than the right; despite similar injuries forty of years ago, I have quite painful osteoarthritis in my right knee, far less in my left; quite nasty varicose veins on my right leg, only very mild on my right. We "lefties" have come in for some stick historically: Latin for "left" is "sinister", right is "dexter" (even though I'm very "dextrous" with my left hand!); an obsolete English phrase for "left-handed" was "cack-handed", dating from before the invention of toilet paper! At school, my late dad (born 1925) was beaten across the hand with a ruler if he had the temerity to write with his left hand. That left him with a lifelong stutter. So generally in life my instinct is simply to reverse hands: if instructions say do something with my right, I do it with my left. Generally, that works very well (although sometimes it raised eyebrows in traditional settings when I lived in the Middle East!). How applicable is that to practice in Qi Gong and Tai Ji? Are there some moves and forms that HAVE to be right-led, as instructed? Or so long as both sides are practiced does that matter? How does that relate to Yin and Yang? Might practice, through harmonising Yin and Yang, eventually make one more ambidextrous? I don't mean "cure" left-handedness, I'm fine as I am, I just mean create something of a better balance. Any advice welcome!
