Using a new form of magnetic resonance imaging (MRI), a team of radiologists has found that sitting up straight puts unnecessary strain on the spine and increases the risk of trapped nerves or slipped disks. Apparently, the ideal angle at which you should be sitting is leaning backwards at an angle of about 135 degrees. That sounds like my preferred position when propped up in bed on a big pile of cushions reading, or lounging in my comfy chair watching TV, but I can't quite see how it's going to work for anyone sitting at a desk using a computer. The study was carried out in a hospital in Aberdeen, Scotland. It involved 22 healthy volunteers with no history of back pain or surgery.
