Do you have pictures of this anywhere? I'm pretty young (28) and worried a bit that I might be going down this path. I seem to be dealing with injury after injury while training for my running races and am fairly convinced that part of it is due to muscle tightness and tension from sitting so much during the day in a bad setup.
Any luck with those photos reboot? I'm building a desk myself and have found that a shorter desk than typical has been a game changer for rsi issues I had. Would be very interested in seeing what you've done.
