Ever since I discovered
python, I have had back problems.
No seriously, the power that is a modern computer and the scripting/programming powers of python (+ libraries) is so amazing that my attention becomes entirely focused on the computer at complete disregard to the rest of my body. Slouched — this is how I am, day in and day out while working on .tex, .py, .c .html etc… files. Not to mention reading.
Bad posture is a serious problem, and I vow to fight. I have had enough. Four years of chronic back pain is enough.
What are you going to do about it?
Stand up straight.
Keep back straight.
