@realDonaldTrump Human rights matter everywhere, for everyone... regardless of race.

Not a single person on this planet chose their race, and not a single person on this planet deserves to be harmed or discriminated against because of their race.

[Thomas Hemingway, M.D. @doc_hemingway]

@realDonaldTrump Genocide is one of the ugliest and most destructive actions humans are capable of committing. I truly hope South Africa can turn this situation around.

@elonmusk The true measure of a society is how it protects the innocent.

Your life is happening NOW.

Not this weekend.
Not when you make a billion dollars.
Not when you land the dream career.
It’s happening now.

It's time to find joy and happiness in the everyday moments of your life.

[Thomas Hemingway, M.D. @doc_hemingway]

@elonmusk I think you're a bit smarter than a retard. In fact, probably a lot smarter.

[Thomas Hemingway, M.D. @doc_hemingway]

@elonmusk Looks like retirement got boring pretty fast.

[Thomas Hemingway, M.D. @doc_hemingway]

@elonmusk This is an opinion I recently heard on the matter that I found quite interesting:

“The larger you population, the higher your chances of minting the next genius (Einstein, Edison, etc) who will change the course of history”

What do you think?

The 12 "Healthy" Habits That Are Actually Wrecking Your Immune System:

✅ Over-sanitizing everything

Constant antibacterial wipes and soaps kill the good microbes your immunity depends on.
A little dirt strengthens your defenses.

✅ Eating “low-fat” everything

Your immune cells require healthy fats and cholesterol for signaling and repair. Low-fat diets weaken immune resilience.

📲 Spread the word by sharing this post with a friend (or to your Stories)

✅ Living on protein bars, shakes, and “healthy” packaged snacks

Most contain gums, emulsifiers, and seed oils that inflame your gut—where 70% of your immune system lives.

✅ Sleeping less to “get more done”

One night of <7 hrs drops natural killer cell activity by up to 70%. Sleep is your immune system’s reset button.

✅ Doing intense workouts daily with no recovery

Overtraining spikes cortisol and depletes immune strength. Recovery days are immune-boosting days.

📲 Follow (or comment “peak” if already following) for a free, 6-module masterclass on reversing your biological age by 10+ years naturally to look and feel your best.

✅ Avoiding the sun

Moderate sunlight raises vitamin D, nitric oxide, and circadian balance—three pillars of immunity.

✅ Eating the same “healthy foods” every day

Lack of diversity reduces microbiome diversity—and a less diverse gut = weaker immune system.

📲 Save this post for later by sharing it with yourself (or clicking “save”)!

✅ Relying on seed-oil-based salad dressings

Highly oxidized omega-6 oils create inflammation that weakens immune defense and increases oxidative stress.

✅ Avoiding all cold exposure

Healthy immune systems adapt to temperature changes. Constant indoor comfort reduces brown-fat activity and resilience.

✅ Drinking loads of kombucha or smoothies daily

Sounds healthy—until you realize they often carry 20–40g of sugar, which can fuel inflammation and dysbiosis.

✅ Avoiding red meat completely

Grass-fed red meat is one of the richest sources of zinc, B12, carnitine, and heme iron—all immune supernutrients.

✅ Under-eating

Very low calories = low thyroid = weak immunity. Your immune system needs fuel.
