Character is not formed out of smart people: it is formed out of people who have suffered.

Cardiac surgeons are trying to compete with cardiologists on convenience.

They're going to lose.

A smaller incision doesn't make it minimally invasive.
It makes it minimal access.

And a mini-AVR?

It actually hurts more than a standard sternotomy because you open the sternum AND break into the rib cage.

"If you think you can compete convenience-wise with a cardiologist who does stents when you do a CABG and your incision is small, you're not fooling anyone."

The game surgeons should be playing isn't incision size.
It's durability. Longevity. Freedom from re-intervention.

That's the competition cardiologists can't win.

But surgeons keep fighting on the wrong turf.

Medicine being called a “noble profession” has been used for years to guilt doctors into accepting burnout, underpayment, and terrible working conditions.

You can go to hell without moving an inch, just focus on what you lack.

You can taste heaven without leaving earth, just rejoice in what you have.

Your coffee habit is doing more than just waking you up!

New research in Nature Communications (2026) shows that coffee actually "rewires" your gut-brain axis.
Here is the breakdown of why your daily cup is a health powerhouse:

1️⃣ Coffee promotes "good" bacteria like Eggerthella, which helps your digestion and keeps the "bad" bugs at bay.

2️⃣ Decaf coffee was specifically linked to better memory and learning, thanks to its rich antioxidants (polyphenols).

3️⃣ Regular caffeinated coffee reduced anxiety and improved focus while lowering body-wide inflammation.

4️⃣ Both regular and decaf drinkers reported lower stress and better moods. It is not just the caffeine; it is the coffee itself!

✅The Bigger Picture:
Recent studies from Harvard and the UK Biobank (2025-2026) also suggest that 2-3 cups of unsweetened coffee daily could lower the risk of Alzheimer’s and Parkinson’s by nearly 30%.

Bottom line:
Your coffee is a complex "superfood" for your microbes and your mind. Keep brewing! ☕️

"Medicine can have extraordinary meaning. But it cannot substitute for being present in your own life. The world may need us as physicians.

But the people who love us need us as ourselves.

And that is the role no one else can fill."

Brilliant - and much love to you

Sleep is a better predictor of longevity than diet or exercise, according to new research. Here are some helpful targets: at least 7 hours of sleep each night, at least 90’ REM, at least 60’ deep sleep, and oxygen saturation at least 94%. https://t.co/SiJ7xL9OIV

I know you know them, but let’s remind ourselves of some additional basic hemodynamic "secrets":

Taking phones off the internet boosts mental health.

People were randomly assigned to block mobile internet for 2 weeks. They socialized, exercised, and read more—and became happier, less depressed & anxious, and more focused.

Being unglued from devices is good for well-being.

ICU Hemodynamic Secrets – The role of ScvO2:

There is not such a thing as a “normal” cardiac output (CO). A CO of 3.5 l/min may be adequate for a 90 years’ old, 100 pounds sedated patient but inadequate for a 40 years’ old, 250 pounds patient with septic ARDS. Ideally,
