Good morning!

Here's your Saturday 7 roundup!

🪥 Why we have to brush:

Why don't wild animals' teeth decay like ours even though we brush and they don't?

It's not because the "average life span [is] shorter than time to tooth decay."

Grok is pretty close.

The answer: a species-appropriate diet won't rot teeth.

📋 What's on my list:

Here are some things on my spring checklist:

Morning sunlight / walk (circadian jumpstart)
Afternoon sunlight / walk (slowly build solar callus before summer)
Barefoot squat holds in the grass (connect and stretch)
Open the windows (breath fresh air)
Light up the grill (beef: breakfast, lunch, and dinner)

But if you have lingering sinus issues from winter try humming.

1 hour a day
4 days in a row

After doing pediatric dentistry, I often do a 10-minute round for cold prevention. (r)

🍯 How to get proof:

These are the US cities where allergies hit hardest.

Some people say local raw honey can help with seasonal allergies.

Peronally, I don't do well with honey, but could be worth a try.

100% natural honey...with proof. 🤣🤣🤣

💡 How to get an advantage:

So many advantages in life come from being willing to look like an idiot in the short term. — Shane Parrish

James Clear put it like this.

Here's the mindset:

Confident enough to start.

Humble enough to keep learning.

Here's the trap:

Too humble to start.

Too confident to keep learning.

🧠 What quote I've been thinking about:

"The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."

– George Bernard Shaw, on why we need unreasonable people

📊 Who put their name on the line:

Morgan Stanley is one of the largest financial institutions in the world and it just filed for its own spot Bitcoin ETF.

That makes Morgan Stanley the first major U.S. bank to file a spot Bitcoin ETF under its own brand, putting its reputation and its balance sheet behind bitcoin.

So, even with Bitcoin sitting well below its all-time high, the floor underneath looks more solid than ever.
