Good morning!

Here's your Saturday 7 roundup!

🧠 How it hurts the brain:

Just 70 years of fluoridated-water drinking later...

A new study details how fluoride induces mitochondrial dysfunction causing neurotoxicity.

The gist: fluoride-induced cognitive deficits involve neuroinflammation via upregulation of C/EBPα and MRPL15, resulting in neuronal pyroptosis from mtROS accumulation due to translational defects. (r)

🪥 How bad is it:

The toothbrush is second only to the mobile phone as the most used consumer product.

Yet, cavities remain the most common disease in the world.

That’s how bad the modern diet is.

More steak, less sugar.

🤐 How does it work:

Thank you to everyone who joined the SnoreBuds and SnoreSealer waitlist last week!

I got a bunch of questions about the new SnoreSealer. This video explains what it is and how it works.

At the end of the video, you'll see a video card linking to another video showing how SnoreSealer works with SnoreBuds for the strongest possible anti-snore effect.

P.S.

While pre-orders officially open in November, I accidentally got the first order from a newsletter reader!

I was running a test order using a setting that was supposed to disable public orders. However, I had recently enabled HSA/FSA payments, and apparently that's a workaround lol.

Good news, both HSA/FSA payments and the test order worked perfectly :)

🧠 What quote I've been thinking about:

"Every problem, every dilemma, every dead end we find ourselves facing in life, only appears unsolvable inside a particular frame or point of view. Enlarge the box, or create another frame around the data, and problems vanish, while new opportunities appear.”
