Slightly related: Does anyone else can't concentrate for long periods of time while sitting in front of a computer? I have mild scoliosis and a fear of varicocele (if that's relevant), and fortunately my work involves implementation of numerical algorithms/problem solving that I can first sketch on a notebook while laying on my bed and finally be coded sitting -on a rush-. Same with reading books. I'm thinking of purchasing a one-sided divan sofa and put it next to my desktop.
