I figured I would take a few minutes to point out that Noam Zeilberger had an excellent paper in POPL this year on Focusing and higher-order abstract syntax. I've spent some time in the past trying to better understand Andreoli's material on focusing and Girard's* Ludics from the judgmental perspective that I became accustomed to in my formative years, but I never really came up with anything. I found Noam's computational interpertation of focusing quite pleasing.
One low tech solution that has really been helping my wrists lately is that I obtained adjustable height desk for my office. The desks that came with my office were definitely far too tall for me (even when my chair at its maximum height).
* Girard seems to have redecorated his website since I last visited.
