I found this youtube video presentation by Esther Gokhale, author of "8 Steps to a Pain Free Back." The video is from her presentation at Google headquarters. The video is nearly an hour and presents a lot of great information.
Also, Chris sent me this link for a podcast interview by Gokhale. This interview is also about an hour long.





Hunter-gatherers really do have beautiful posture. I guess that’s another thing we’ve sacrificed by our modern lifestyle. I’ve always wondered whether it’s just muscular or if it has a skeletal component as well.

It’s a great read.
