The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
As people age and their working memory gets worse and their ability to focus gets worse, the number of attentional blinks that they carry out goes up, and there are now studies exploring whether or not the simple meditation like practice of 15 to 20 minutes or so of sitting and just quietly resting and paying attention to one's breathing and internal state can also offset some of that age-related what is called cognitive decline.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So what these data tell me is that regardless of whether or not you're a child or you're an adult, whether or not you have ADHD or not, whether or not you're experiencing age-related cognitive decline, or you would simply like to avoid age-related cognitive decline, a simple practice of taking 17 minutes sitting and paying attention to your internal state, just interocepting, registering your breathing, registering the contact of your skin with whatever surface you're on, can forever rewire your brain to be able to attend better and possibly even offset some of that age related attentional drift.
