Years ago, I had to use one to work, because I had chronic back pain for decades (starting in 6th grade), then in my 30s I threw my back out, and for months I couldn't sit without excruciating pain. Standing wasn't great, but still: much better.
When did I throw my back out? It was Thanksgiving Day, of course. #stress
@jrefior it was absolutely crucial to my hernia recovery. I started developing a really bad slouching problem while sitting because my internals were messed up. Standing was totally fine.
