You “die” when your heart stops.

Heart disease is the leading cause of death, more than all forms of cancer and accidents combined.

Here are 3 doctor-approved fixes to make your heart 20 years younger:

Problem #1: Your arteries are hardening.

As you age, blood vessels stiffen.
This slowly increases blood pressure and heart strain, entering a vicious cycle.
Smoking, sugar, and stress further accelerate this process.

The ultimate goal: Keep your arteries elastic and young.

Problem #2: Endothelial dysfunction

The endothelium controls vascular tone and blood flow.

When it’s inflamed, nitric oxide (NO) drops.

Less NO means:
• Constricted vessels
• Higher blood pressure
• Faster arterial aging

One of the simplest ways to support your?

Nitric Oxide.

It relaxes blood vessels, enhances oxygen delivery, and reduces strain on your heart.

I use this exact one daily👇

Problem #3: Your heart is inflamed, not just clogged.

Cholesterol is part of the problem.

But inflammation is what makes plaque dangerous.

Inflamed plaques rupture.

That’s what causes heart attacks.

Chronic stress, poor sleep, and bad diet keep inflammation high.

Fix #1: Lower resting heart rate and blood pressure with exercise

Target:
• Resting HR: 50–60 bpm
• BP: <120/80

How:
• Zone 2 cardio: 30–45 mins, 3–4x/week
• Breathwork: 5 mins/day of slow breathing (5–6 breaths/min)
• Sleep: 7–9 hrs, consistent bedtime

Fix #2: Eat to fight inflammation and improve insulin sensitivity

Fix both by:
• 30g protein per meal
• 25–30g fiber/day (plants, seeds)
• Cut sugar & refined carbs
• Add omega-3s (salmon, sardines, flax)
• Get 7–9 hrs sleep nightly

This reverses vascular aging.

Fix #3: Activate your parasympathetic system daily

This restores heart rate variability, lowers resting HR, and reverses vascular tension.

Start with:
• 5 mins of slow breathing (5–6 breaths/min)
• 10 mins of morning sunlight
• 30 sec cold showers
• Walks in nature

Fix #4: Improve nitric oxide (NO) levels

NO is the key molecule for vascular health.

It opens up your blood vessels, delivering oxygen to your heart.

Your body produces NO every day, but by age 40, your NO levels drop by 50%.

Without enough NO, your heart ages even faster.

In 1998, 3 U.S. scientists won the Nobel Prize.

One of them told Dr. Nathan Bryan:

“If we can restore Nitric Oxide production, it’ll change the world.”

25 years of research later, he’s still proving it true.

If you want a 100% natural supplement for Nitric oxide production, this is the best one I've found:

It's the best investment for me at 40👇

Bonus: Get your CAC score

You can't fix what you can't measure.

The coronary artery calcium (CAC) score is the #1 predictor of heart disease risk.

Better than cholesterol and age.

One 5-minute scan can show if your arteries are aging or reversing.

Grey hair is easy to fix.

It’s not caused by genetics or aging, but years of neglect to feed their hair.

Here are 6 science-backed foods for healthy hair today:

1. Eggs (with yolk)

Nature’s multivitamin for your hair.

Biotin, zinc, sulfur, and protein in one.

Biotin builds keratin, and sulfur boosts shine and hair structure.

2/ Liver (beef or chicken)

Nature’s most concentrated source of hair nutrients:

B12, folate, iron, copper, and biotin.

Supports red blood cell flow, melanocyte health, and keratin production.

Everyone wants to control how long they live.

But most longevity advice are flat-out wrong.

Here are 10 science proven methods to live longer, look younger, and stay sharp:

1. Muscle > Cardio

Muscle mass is the #1 predictor of longevity in older adults.

• Prevents falls
• Supports glucose control
• Boosts testosterone and immune strength

Strong is how you stay long :)

2. Fix your sleep timing, not just duration

Sleeping from 10PM–6AM aligns with circadian repair:

• 10PM–2AM → physical repair (hormones, muscles)
• 2AM–6AM → mental repair (memory, cognition)

Late sleepers miss key regeneration windows.

Your body is starving for this ONE nutrient.

It's not a vitamin, mineral, or protein.

It's a natural substance that slows aging in adults and transforms newborns' development forever.

Here's what it is (& how to get enough of it):🧵

It’s called Nitric Oxide (NO).

Your body makes it every day.

NO widens blood vessels and fuels cellular energy, providing oxygen.

But by age 40, your levels drop by over 50% naturally, which means:
• Less oxygen for performance
• Weaker blood flow
• Higher risk of disease

Newborns without enough NO can suffer permanent damage.

In hospitals, doctors give nitric oxide gas to save babies who can’t breathe.

In adults, it powers neuroplasticity (the ability to learn, adapt, and grow).

Your brain alone uses 20% of your body’s oxygen.

This might save your life:

If your thyroid is broken, you’ll feel tired, fat, depressed, and cold no matter what you do.

But 2 out of 3 people have thyroid issues & have no clue they do.

Here’s what’s going on (& how to fix it before it destroys your health): 🧵

Thyroid is a small butterfly-shaped gland in your neck.

But it’s the master switch of your metabolism.

It runs your:
• Body temp
• Weight
• Energy
• Digestion
• Mood
• Fertility

If it's off, everything else suffers:

How it works:

Your brain sends a signal: TSH (thyroid-stimulating hormone)

Your thyroid makes two hormones:
• T4 (inactive)
• T3 (the one that actually gives you energy)

T4 gets converted into T3 in your liver & gut.

If that conversion fails, you feel like hell.

Testosterone is the fountain of youth for men.

Here are 5 tested and natural ways to rebuild your testosterone (bookmark this):

1. Lose fat

Fat tissue converts testosterone into estrogen.

Losing fat naturally increases testosterone production.

In one study, men who lost 17 pounds through diet and exercise increased testosterone by 46 percent.

Also remember to grow muscle…

Lifting heavy weights triggers a hormonal cascade that boosts testosterone and growth hormone.

Especially compound lifts:

• Deadlifts
• Squats
• Pull-ups
• Overhead press

Train 3–4x/week with progressive overload.

You were lied to.

This Harvard anthropologist spent 19 years proving your weight gain has nothing to do with aging.

Here are 6 metabolism myths keeping you fat:

Myth 1: Metabolism slows down with age

Pontzer’s 2021 study analyzed data from 6,400 individuals from birth to age 95.

Metabolism stays rock steady from age 20 to 60.

Your weight gain isn’t aging.

It’s because you move less, sleep worse, eat more processed food, and get more stressed.
