I've spent way too much time at the computer from an early age. I love my job, but wow, sometimes it requires me to put in some ridiculous hours at the keyboard. Then one of my favorite pastimes is PC gaming, where I sit at a desk for hours yet again.
Not a great combo.
As a result, I've suffered through all manner of hideous acronyms, including TMJ, RSI, and LBP (lower back pain), over time. Generally, I've been able to manage the problem with better ergonomics, a quality chair, and frequent breaks. Still, at the end of a long stretch during GPU review season or the like, I'm sometimes discovering new ways to feel pain. (When I move my arm here, I feel burning-hot-poker pain on the other side down there.)
New game releases are another danger. Back when Half-Life 2 came out, I initiated a multi-day quest that ended in agony. Never did finish that game, but it nearly finished me.
I'm pretty sure I'm not alone. Lots of computer enthusiasts deal with these problems—and at increasingly early ages, I suspect.
So . . . tell us where it hurts. Where do you feel the consequences of your computer time? Have you been able to manage the pain? Has the rise of mobile devices like tablets helped or hurt the cause?
