My older friend just got a terrible surgery due to some kind of issue with her tailbone and I'm conscious about my own sitting position now. I have a terrible posture and I tend to sit really on the tailbone all day at the computer while at study at home. I often gather up my legs on my chair, with my shin pressed against the table edge, (I use kitchen table for my work) as I type.on my computer. Is this really bad? Why do I feel more comfortable scrunching up like that?
Also I like working in bed, my upper body propped up but sitting in a half-laid back posture with my lower spine and tailbone getting the weight and pressure. Is this posture bad?
