If you're thinking slower than you want about work, then maybe it's because the work isn't worth thinking about. If you're forgetting things at work, then maybe it's because they weren't worth remembering. Absent a serious health condition, a mind won't just fade away when it knows it's needed and is serving an important purpose. Try introducing a little bit of disruption into your life to make things interesting again. The struggle is what keeps us going.
