"Researchers aren't sure why prolonged sitting has such harmful health consequences. But one possible explanation is that it relaxes your largest muscles. When muscles relax, they take up very little glucose from the blood, raising your risk of type 2 diabetes."

"Sitting can also increase pain. Even if you're reasonably active, hours of sitting—whether reading a book, working on the computer, or watching TV—tighten the hip flexor and hamstring muscles and stiffen the joints themselves. Overly tight hip flexors and hamstrings affect gait and balance, making activities like walking harder and perhaps even setting you up for a fall. Plus, tight hip flexors and hamstrings may contribute to lower back pain and knee stiffness, scourges that many people suffer with every day."
