Something I've come across recently, which seemed worth sharing - especially for folks of a certain age (like myself) who have spend a lot of time on a computer, reading, writing, etc. Typically western slouched postures which can result long-term in chronic aches and pains. The little-known "Egoscue" - simple yoga-like postures/stretches, but designed for such modern problems (eg workplace/computer posture, carpal tunnel, etc). Pretty straightforward (not a cult or a "grift"!) & certainly seems to work (or at least it did for me). The usual book, youtube videos, etc, depending on ailment.
