Thought I would mention the new iOS development podcast, Under the Radar, again this week as it hits on a topic that many developers skip over. Ergonomics isn't something you think about until you have an issue with your back, wrists, or whatever. It's like listening to music too loud when you are younger and paying the price as you get older.
Personally, I developed back problems a few years ago from sitting most of the day and having a long commute. I have mostly remedied the trouble by building a standing desk. I also learned the trick of drinking a lot of water at my desk. This has the double benefit of keeping you hydrated and forcing you to break from what you are doing to go to the bathroom.
Coding for 6 hours straight without moving is bad for you. Do something about it before you develop injuries that can serious alter your quality of life.
