My posture is rather poor. I have scoliosis. I had to wear a back brace for 3.5 years. It was hard plastic that went high up under my armpits (I always had soars) and down to the fold of my legs. I could only take it off to shower. It was the most horrible thing ever, and I wouldn't wish it on anyone. I had a 42 degree curve in my spine, now it's down to 38 degrees. 3.5 years of torture to improve a lousy 4 degrees, it was not worth it. I had to wear it from the middle of my 6th grade year until the beginning of my 10th grade year in school.
