Guy complains about being prone to back pain (despite his adamant stance about the correct posture) then says something like this:
> We live in a gravitational field, and when our bodies are out of line with the vertical, certain muscles will have to work harder than others to keep us upright. This can result in undue fatigue and discomfort that can outlast the strain that caused them.
I have given myself back pain once. Lasted few months and hurt like hell when getting my head up from the bed (and other similarly straining activities). Went away while after I eliminated the cause. Which was most comfortable chair I've ever had.
Chair was perfect and supported me perfectly. I was sitting for hours in it. But my pose was static. Why move out of optimum? This caused small stabilizing muscles near my spine to weaken (while the large ones stayed fairly strong). Then it was enough to lift something bit awkwardly to cause significant damage to them that took few days to heal (or even weeks before I discovered which exercise to apply to work the small deep muscle that hurt).
I'm slouching since forever. But I also wriggle in my chairs and get up often. I found good chairs to be those that allow for that.
