An interesting presentation about how sitting may actually be killing you...

Fascinating stuff - sitting may be killing you!

A short presentation that I came across by being a fan of Dan Millman on Facebook. If you don't want to go through the entire (but short) presentation, just know that it's a good idea to interrupt sitting whenever possible and stretch, walk, do jumping jacks, whatever, just to get the blood flowing again. The human body simply wasn't made for sitting...
