I saw comments online about dangers of…

"anger turning into RUMINATION. […] Be angry, say your peace [sic] or learn about said person and adjust your boundaries and relationships, but rumination is a killer, it erodes you."

Bizarre! I've known #rumination, which for humans means thinking deeply, to be a good thing. I searched & found several sources refer to rumination only related to negative thoughts. Even "reputable" sources like psychiatry.org.

No, it's not bad! Go out & #ruminate!
