Worked on a boat (at work, had our engine, minor issues) doing plugs and wires, was a mid deck jet boat which makes things a pain in the rear...
On the getting old thing, on Saturday I was squatted down working on the finish mower for my tractor and all the sudden my left knee popped, didn't hurt for like a day and now there's apparently some fluid pressure in there since it now hurts to squat down and even more when I go to stand up... and I'm only 41! Every now and then I sleep wrong and can't look left for a couple days, then even dumber when my pillow pulls an eye open a little and dehydrates an eyeball which seems to last a couple days... Calendars are mean...
The other thing I've been working on is a sheet metal cover for the wires and stuff under the external power panel for the house, last September when the inspector was here doing the final on the shop he mentioned doing that, don't rush me!

. The electricians broke the plywood junk that was there when I moved in so I opted to make a sheet metal version... I've had the material for at least 6 months, I cut the side pieces and took them to work, a coworker has a nicer brake than we have at work so he bent the flanges. Tonight I cut out and marked the front face so he can bend one more 90 and one with just a crease then I get to do some final trimming and drilling (as well as putting in some rivnuts for fun), scuffing then paint then install
Oh, and my finish mower for the tractor lost a belt idler a couple weeks ago, got the replacement today and installed that, I got a new belt but decided to run the old one till it dies... at least I have a replacement...
