A December 2011 LessWrong classic. Argues that ergonomics is a basically solved problem and yet most "techno-geek" rationalists ignore it. If you treat your career as 80,000 hours, you'll work even more hours sitting; investing serious money in a chair, monitor height, keyboard, mouse, and desk setup pays off across hundreds of thousands of hours and reduces fatigue, RSI, and headaches. A short, direct rationality-applied-to-real-life argument.
