It's almost comical how often this is overlooked. But then again i have not seen studies or abundant testimony about it so maybe it is just expected. But postural damage leading to chronic fascial tension is probably the single most overlooked health issue today leading to most chronic diseases we as a population experience.I’d bet posture also plays a role. They weren’t sitting in chairs all day hunched over.
I suggest everyone to watch through the lecture series at www.stressmechanism.com and draw their own conclusions on how this happens.
