Correlation or causation? The article doesn't specify whether the subjects' brain sizes were measured prior to the study.
I understand the difference, but in this case it’s not a good look for TV viewing regardless

#14Now I'm curious if it matters what you watch.
Yeah... like, does watching an Attenborough documentary or two offset many hours of marvel movies? Asking for a friend.

probably not as much as doing anything non sedentary

#17I guess that means we are lucky that TVs weigh so much less now.

The linked paper suggests brain sizes were only measured once at visit 5.

What does that even mean? If people with cognitive deficits have a powerful idiosyncratic preference for pineapple juice, that's not a bad look for pineapple juice.

#20One big concern for me in this article is, the MRI scans were not taken during the start of the study. But, I couldnt eliminate this because the pattern (of reduced white matter in brain) seem to hold true across the pool of 1700 people.
Most curious part of in this article is the active vs passive sitting distinction. Occupational sitting (or performing intellectual activity while sitting) correlated with better brain scans and white matter.
This makes sense, if I view it as consumption vs processing thing.
TV is pure consumption, Intellectual work requires output and creation.
If this thesis holds, the rise of AI tools is a bit concerning for knowledge workers. We are shifting from active creation (writing code, writing articles, designing, etc) to passive consumption and curation (reviewing AI generated content).
Will be interested to learn more on how this study unfolds further.
