My lower back hurt; I couldn't sit still; it hurt even more after the massage

I hadn't done physical labor for a long time, then suddenly took on heavy work and couldn't hold up. I needed to exercise properly from now on, or I really would become useless. Back in the day, I was a beast who could pull an all-nighter, then keep up with ten thousand words without feeling much at all. After not doing it for several years, I'd only become more and more useless.

Everyone, make sure to exercise well. I was going to start too. A healthy body was everything.
