Resistance Training Counters Age‑related Muscle Loss and Restores Protein Sensitivity
Muscle loss with age is common, but much of that decline is driven by inactivity, not aging alone. On average, we reach peak muscle mass somewhere between 20 and 30, then lose about 8% per decade after that. By the time many adults reach their 70s and 80s, they may have only 60–80% of the muscle mass they had at 30. A big reason why is anabolic resistance. As we get older, muscle becomes less responsive to amino acids, one of the key signals for building and maintaining muscle. This is where resistance training becomes non-negotiable. It's one of the main signals that tells muscle to grow. And just as importantly, it helps re-sensitize muscle to amino acids, so the body responds to protein more like it did when you were younger.
Reverse Osmosis Cuts Microplastics, Add Mineral Drops
One of my first recommendations for people wanting to reduce their microplastic exposure at home is a reverse osmosis filter. They remove 99%+ of microplastic particles and other contaminants. But they also remove trace minerals, so adding them back with mineral...
One Week Plastic-Free Diet Slashes Hormone Disruptors 60%
A “plastic-free diet” cut endocrine-disrupting chemicals in the body by up to 60% in just 1 week. Participants in a recent study switched to low-plastic food, plastic-free kitchenware, and screened personal care products for 7 days. Urinary BPA fell by 59%, and...
Choose Triglyceride Omega‑3s for Superior Absorption
Not all omega-3 supplements are created equal. Most fish oil on the market is in ethyl ester form, which is cheaper to produce after purification. But it's not found in nature and is less bioavailable. What you want is triglyceride form omega-3s....
Stop Eating Three Hours Before Bed for Better Sleep
One of the simplest things I do for sleep is to stop eating about 3 hours before bed. It's something that’s supported pretty consistently in the research. When you eat (especially a large meal), you’re activating the sympathetic nervous system... not what...
Strength Training Boosts Mental Resilience and Stress Tolerance
One of the biggest benefits I noticed after starting to strength train seriously was the "mental fitness" I gained. Doing tough lifts is challenging enough that it changes how the rest of my day feels. I handle stress better, things don't...
30‑Minute Sauna Spike Boosts Immune Cells
Sauna bathing mobilizes circulating immune cells. A single 30-minute session at ~165°F (enough to elevate body temperature to 101°F) increased levels of several immune cells including lymphocytes and neutrophils for up to 30 minutes. This occurred in non-users and people who used...
Five Essential Supplements Everyone Should Consider
I'm obviously a big fan of supplements. But if I had to narrow down my list to just 5 that I think most people should be taking, they'd be: - Omega-3s - Magnesium - Vitamin D - Creatine - A high-quality multivitamin
Urolithin A Enhances Mitochondrial Health and Endurance
I'm fascinated by Urolithin A. It's a compound that stimulates mitophagy (mitochondrial autophagy), helping clear out and replace damaged or dysfunctional mitochondria. Recent studies show that urolithin A improves endurance performance and even keeps immune cells "younger" with age. The data are early...
Latex Fails; Nitrile Blocks BPA From Thermal Receipts
Why won't latex gloves protect you from BPA/BPS in thermal receipts (or EKG paper)? Latex (natural rubber) is permeable to BPA/BPS. These chemicals dissolve into the latex polymer and slowly migrate through to your skin, especially with repeated handling throughout the...
The Optimal Omega-3 Protocol for Heart, Brain, & Longevity
The presentation focused on an evidence‑based omega‑3 protocol designed to improve cardiovascular health, cognitive function, and overall longevity. Drawing from decades of research, the speaker highlighted how omega‑3 fatty acids—particularly EPA and DHA—interact with vitamin D and resistance training to decelerate...
Peakspan: Targeting 90% Peak Capacity Across Lifespan
"Peakspan" should be the longevity marker everyone's talking about. It refers to how long we can maintain 90% or more of our peak capacity in one of several health domains like muscle strength, cognitive function, or fertility. And it recognizes that these...
Visceral Fat Loss Preserves Brain Volume and Cognition
This study on visceral fat loss blew my mind... It found that sustained visceral fat reduction over years was linked to preserved brain volume and cognitive function in middle age. They tracked people for up to 16 years, and those who lost...
Screen Overload Erodes Reflection, Embrace Boredom for Meaning
Our devices are changing how we use our brains. @arthurbrooks makes a compelling point that constant device use fills every open moment with stimulation, and that may come at the expense of reflection, meaning, and self-understanding. Boredom feels uncomfortable, but it also...
Happiness Comes From Wanting Less, Not Achieving More
Success doesn’t truly make us happier. Why? Our neurobiology is wired for progress, not arrival. The dopamine system rewards the pursuit. Once a goal is reached, the brain resets and the target moves. It’s what @arthurbrooks calls the “striver’s curse.” You work...
