Posted below is Pack Matthews' TEDx talk. He talks about the health offascia, the "sitting is the new smoking" research, and the research linking longevity to one's ability to sit and rise from the floor without using hands or knees--and gives a great demo of this! Pack is the inventor of the Soul Seat™, a great option for people whose work requires that they sit all day. The design invites you to squirm and stretch while you sit. I'm putting one on my next letter to Santa!
