I actually freaked out recently when my wrist went really sore to the point of almost getting blocked.

Since i got an ergonomic keyboard, slowed down my typing pace (whilst aiming to do less typos) and generally try not to use my mouse at all everything's fine again but it scared me a bit.

I'm trying to have small incremental changes but it is pretty difficult sometimes as I have to deal with user support / management tasks and sysadmin tasks on top of my dev duties. Small institutions, yaaaay!
