Yes, and my mother was once stuck in a lift for three hours in a department store when she was a girl. She is unfazed by the whole thing, but the story still creeps me out. I tend to avoid them when possible. But back to the OP, I think in general knowing how to stretch and how to sit down is so important now that so many of us spend so much time in front of a screen sitting at a desk. The damage we are doing to our backs, eyes and necks without realizing! I have started working from home a few days a week now, just so I can go for walks and wanders when I feel I need to get the blood flowing again. I have recently purchased some comforters from this site
as I was suffering from a bit of back ache before. When it really gets bad I just snuggle up in bed and work there! If only we could take out duvets into the office!!!
