I got rid of the behemoth.
When I moved my day off from Friday to Monday, I still wrote my sermons on Friday, but no longer on my day off. As a result, I no longer wrote them at home. Which in turn meant I came home with all kinds of bursitis and odd aches and pains from trying to type a few thousand words in a couple of hours at a non-ergonomic workstation. Ergo, the stand-up desk (“bar table”) I use at home must be more ergonomic than the gigantic desk at church.
So for my birthday, more or less, Mrs. Mess of Pottage bought me a new desk. My arms feel better, but my feet are sore. (The blue shock-absorbing mat at the bottom of the desk is a late-afternoon addition.)
