Outlive: The Science and Art of Longevity

Sat, 12 Aug 2023 00:00:00 +0000

Most people picture longevity as adding a few years at the end. Peter Attia flips that: the goal isn’t to avoid death so much as to avoid spending your last decades unable to climb stairs, carry groceries, or get down on the floor to play with your grandchildren. He calls the difference healthspan versus lifespan, and the single most powerful lever on it is what you do right now — above all, how you train your body for the demands of being ninety.

Born to Run: A Hidden Tribe, Superathletes, and the Greatest Race the World Has Never Seen

Fri, 01 Dec 2023 00:00:00 +0000

Distance running should not wreck your body. For most of human history it didn’t. Your anatomy was shaped by persistence hunting—chasing animals across open ground until they dropped from heat exhaustion—which means the body is engineered to cover long distances. So why do 65 to 80 percent of modern runners get hurt every year, with doctors telling the injured to simply stop? Christopher McDougall’s answer is that the fault isn’t in running. It’s in the cushioned shoes that numb the feedback your feet need, and in treating running as a chore instead of the pleasure it was born to be.

The 4-Hour Body

Sat, 18 Oct 2025 00:00:00 +0000

Your body responds to what you eat at a hormonal level, not just a caloric one, and most of what happens in a gym is wasted effort. That single reframing sits underneath Timothy Ferriss’s decade of self-experiments, a project he spent more than $250,000 testing and refining. The aim was never to do more. It was to find the Minimum Effective Dose: the smallest change that produces the outcome you’re after. Push past that threshold and you often go backward.

ADHD 2.0: New Science and Essential Strategies for Thriving with Distraction

Sat, 18 Mar 2023 00:00:00 +0000

An ADHD brain isn’t defective; it’s a racecar with a pushcart’s brakes. The distractibility, impulsivity, and restlessness come bundled with energy, creativity, and drive, and the right strategies turn that combination into a genuine advantage. Recent fMRI research points to why the wiring feels the way it does. Two networks handle your thinking: the task-positive network, which fires when you’re focused and in the zone, and the default-mode network, which runs imagination, memory, and planning for the future. Everyone toggles between them, but with ADHD the switch is stubborn. You might lock onto one task and forget every other responsibility, or your imagination might latch onto shame and disappointment and loop. When you’re stuck spinning in negative thoughts, you’re trapped in the default-mode network. The exit is physical: take a walk, do a puzzle, wash the dishes — anything that gets you out of your head.

The Age-Proof Brain

Sun, 21 Sep 2025 00:00:00 +0000

The age of your brain and the number on your birth certificate are two different things. The proof is a group Milstein calls SuperAgers: people past 80 whose minds work like someone decades younger. Significant cognitive decline, it turns out, is not a normal part of getting old. An estimated third of current dementia cases could have been prevented by changes in how people live. That’s the whole premise here. Your sleep, your meals, your movement, and your relationships are quietly voting, every day, on whether your brain stays sharp.
