我很相信坐在那会谋杀你的腰椎的椅子上花好几个小时整理费用报告会是你的理想工作!
But working on any mobile device in bed for more than an hour without lumbar support , with the neck bent forward too sharply , or with the arms and hands suspended at an awkward angle , is likely to cause aches and pains .
A lumbar puncture - a needle in the spine - may also be used to check protein levels in the brain , which tend to be higher in alzheimer 's than with frontotemporal dementia .
