I thought this late comment from Ingrid was so interesting that it needed to be brought up front for your perusal:
"I’ve only just discovered this blog and was reading back. I can’t
resist making a very late comment, even though no one will read it.
I just wanted to say that it’s perfectly possible to raise your arms
above your head without lifting your shoulders, you just can’t have
your arms skimming your ears. The method is taught all over the world in ballet classes. Just look at a photograph of a ballet dancer (male or female) with one or two arms above his or her head, the shoulders
are never raised. Ballet teachers also like to explain posture by telling pupils to imagine themselves wearing a corset. One aspect of this is bringing your breastbone forward and up, and your shoulder blades together, which is exactly what the 18th-century corset does."
As soon as I have another six or ten cups of coffee, we will return to our regularly scheduled programming.
