Threw my back out yesterday trying to move a stubborn gate that had seen one too

Threw my back out yesterday trying to move a stubborn gate that had seen one too many seasons without oil. Ended up staring at the ceiling and had some time to think. Amazing how something so simple can stop you in your tracks. Reminds me of how a small piece of metal makes all the difference in a rifle. Found any little problems lately that made you slow down and take stock?
