One of the most difficult things to do in modern life is sit without discomfort and pain.
The main issue is one of pressure. Our brain no longer senses the ground beneath your feet. Without that sense of the ground, your body will extend (your back muscles will tighten and your lumbar spine will arch) into the right BC or PEC pattern.
Once you extend, you lose your left diaphragm, your ribcage becomes restricted, and you rely on compensatory breathing patterns: in short, you use your neck for breathing. Not good.
Couple neck breathing with staring at a computer all day, which also increases neck tension, you've got a perfect storm that created all sorts of neck, shoulder, and back pain.
