Sitting straight ‘bad for backs’
I first saw this on KTRV Fox 12 News at Nine. The BBC has an article about Scottish and Canadian researchers using MRI to study the effects of posture and back strain.

Disk movement was found to be most pronounced with a 90-degree upright sitting posture.
It was least pronounced with the 135-degree posture, suggesting less strain is placed on the spinal disks and associated muscles and tendons in a more relaxed sitting position.
The “slouch” position revealed a reduction in spinal disk height, signifying a high rate of wear and tear on the lowest two spinal levels.
When they looked at all test results, the researchers said the 135-degree position was the best for backs, and say this is how people should sit.
I could have saved the researchers a lot of time and money. I sat in my chair and stared at a computer for five years at Micron and this 135-degree posture position was definitely my favorite and most comfortable.
Next time someone tells you to sit up straight, tell them it isn’t good for your health!
