Great article. I’ve been looking for research validation of this specific point. And I found this blog challenging the mere existence of the Stanford Research mentioned here: https://neurocritic.wordpress.com/2016/12/31/complaining-shrinks-the-hippocampus-the-study-that-doesnt-exist/

I appreciate if you can share your source for this notion of “complaining shrinks the hippocampus.” Cheers, Gustavo
