Thank you for your ideas and the wonderful and polite way you are writing here. God knows we need people like you here because pretty much every member here is struggling through mental issues because of EC. That being said, you have made good points about posture. I have by no means a good posture, however, I am fairly active, much more than many of the student athletes at my college. However, that has made little impact on my EC. But of course, that doesn't mean that proper posture which does open up the channel of energy throughout the body won't help out others. I mean why not try it right? You can ONLY look better and more confident with good posture and that will at the very least, elevate your mood.
Thanks for being humble and writing formally, and know that it is appreciated.
