This started as one of those random self-improvement moments.

I was at my desk and suddenly became hyper-aware that I sit like a shrimp. Back curved, neck forward, shoulders doing whatever they want. So I thought, okay, I’m going to fix this. Right now. New me.

I straightened up. Shoulders back, chest out, core engaged. I even Googled “correct sitting posture” and tried to match the diagram like I was being graded.

At first it felt great. Like I had unlocked some kind of adult achievement.

Then my brain decided that if I relaxed even slightly, I’d immediately revert back to being a shrimp forever. So I didn’t relax.

For three hours.

I sat there rigid like a museum mannequin. Didn’t lean back, didn’t shift, didn’t even reach for my water properly because that would break “form.” My coworker asked if I was okay because I hadn’t moved in a while and I said, through clenched abs, “I’m fixing my posture.”

Eventually I stood up and my entire body locked up. My back cramped, my legs felt like I’d been bracing for impact, and I had to walk like I’d just aged 40 years in one motion.

Turns out posture is something you adjust… not something you brute force like you’re trying to win a staring contest with your own spine.

TL;DR: Tried to fix my posture and instead sat like a statue for hours until my body revolted.
