At 70 years old, pushing hard toward my wild goal of living to 200 with The 200 Year Life Project, sleep is sacred—it's when the body repairs DNA, clears brain waste, and rebuilds for another day of optimization. But modern life is noisy: traffic, neighbors, snoring partners, even the hum of appliances. That's why I wear high-quality Loop Quiet earplugs every night, combined with my blackout sleep mask. Blocking noise isn't optional—it's a game-changer for deeper, more restorative sleep.
Noise: The Silent Sleep Killer
Even low-level sounds disrupt sleep architecture. They trigger micro-arousals—brief awakenings you might not remember but that fragment deep and REM stages. Over time, this leads to poorer recovery, higher stress hormones, and accelerated aging.

At 70 years old, on my relentless mission to live to 200 with The 200 Year Life Project, I'm always hunting for nutrient-dense additions that pack a serious punch against aging. That's why cod liver oil is a daily staple—I take one teaspoon straight (or in capsules when traveling) for its unbeatable combo of omega-3 fatty acids (EPA and DHA), vitamin A, and vitamin D. This isn't trendy fish oil; it's the real deal from cod livers, delivering anti-inflammatory power, heart protection, bone support, and immune resilience in one spoonful.
At 70 years old, charging full speed toward my goal of living to 200 with The 200 Year Life Project, I've learned that the simplest metrics often reveal the biggest truths about health. Grip strength—the force you can generate with your hand muscles—has become one of my obsessions. It's not just about crushing a handshake; research shows it's a powerful indicator of overall health, frailty, and even lifespan in seniors like me.
Grip strength is often called a “biomarker of health status” because it reflects your overall muscle function, which ties into everything from mobility to metabolic health. Measured with a dynamometer (that's the device I use), it gauges how much force your hand can apply—typically in kilograms or pounds. For seniors, low grip strength is a red flag for accelerated aging, higher chronic disease risk, and shorter lifespan.

What Is Grounding (or Earthing)?
Your core body temperature naturally drops by about 0.5-1°F in the evening as part of the circadian rhythm—that's the signal telling your brain it's time to wind down. A hot shower (or bath) accelerates this process in a clever way: The warm water dilates blood vessels, pushing heat to your skin, hands, and feet. When you step out, that heat dissipates quickly through evaporation and radiation, causing a rapid drop in core temperature—mimicking (and enhancing) the body's pre-sleep cooldown.
Here's my current supplement lineup:
I'm all in on stacking evidence-based habits that extend not just lifespan, but vibrant healthspan. One of my absolute favorites — and a daily non-negotiable — is my four-cup morning coffee routine. I've shared details across several posts and videos, but today I'm pulling it all together into one comprehensive summary.
