THERE ARE REMARKABLY SIMPLE WAYS TO DO THIS.
I KEEP NOT DOING THEM.
...hi. My body is currently reminding me of the truth of those first three lines. I had a quiet weekend — a boring weekend, honestly — but I also quietly helped a friend move. A few things. Just a few things. On Sunday, said friend was in the final stages of moving items out of the house she's leaving (she's bought a place in another part of the country), and the person who'd planned to help her with a few large items was too sick to get out of bed, let alone move around bookshelves or futons. Luckily I was available, and I drove up to my friend's place.
By "just a few things" I mean we were done moving stuff after about 10 minutes. Huh. I'd expected that to take longer.
If it had taken longer, I'd really be feeling it this morning, but no, there's mainly a little ache. I felt a little ache later that night — after driving further into North Portland, hanging out at a library to pass time, having dinner at a theater-pub, briefly visiting with other friends who came to that theater-pub for a film, then heading back to East Portland, stopping along the way for groceries — and had to remind myself I'd moved a few big things. I'm allowed a little ache.
I've ached much, much more, trust me. And a little ache would be worth it to have more upper body strength...more strength in general, in fact and of course.
I'm writing this here to remind myself. I hope Future-Me is glad I did.
