My unified theory of aging and disease Claude AI did this, using papers I selected as references. See what you think. The Master Switch: Insulin Resistance Facchini (2001) showed insulin resistance predicts virtually ALL age-related diseases. That's the trunk of the tree. Everything else branches from it. What drives insulin resistance? Kohrt (1993): belly fat, not age. Waist explains >40%, age <2%. Blagosklonny (2006): chronic mTOR activation. Overfeeding keeps mTOR on, cells grow when they should repair. PD's iron paper: iron accumulates with age, activates mTOR, and iron + insulin resistance are co-morbid. What does insulin resistance cause downstream? Khan (2017): high insulin drives high PAI-1, which drives senescent cell accumulation, shorter telomeres, faster aging. The Amish with half the PAI-1 lived 10 years longer. DePalma (2010): high ferritin + inflammation = vascular death. Iron and insulin resistance amplify each other. Madeo (2015): when mTOR is chronically on (from insulin resistance + iron), autophagy is suppressed. Cellular garbage accumulates. Aging accelerates. What reverses it? Lim (2011): type 2 diabetes reversed in ONE WEEK with caloric restriction. The damage isn't permanent. Gibala (2020): 5 minutes of hard exercise produces the same fitness gains as 50 minutes moderate, and improves insulin sensitivity through pathways that bypass insulin entirely (GLUT4). Fisher (2011) + Wolfe (2006): muscle is a metabolic organ that acts as a glucose sink. More muscle = more insulin sensitivity. Resistance training is the most efficient way to build it. What's been wrong all along? Ravnskov (2016) + Siri-Tarino (2010) + Ramsden (2016): the cholesterol/saturated fat hypothesis was wrong. Higher LDL in elderly = lower mortality. Replacing saturated fat with seed oils increased death. The medical establishment spent 50 years focused on the wrong molecule while insulin resistance was the actual killer. PD's iron paper ties the bow: Iron is the hidden variable connecting all of it. It activates mTOR (Blagosklonny), inhibits autophagy (Madeo), worsens insulin resistance (Facchini/Kohrt), increases PAI-1 and senescence (Khan), and accumulates silently with age in every man and postmenopausal woman. The life-extending compounds (curcumin, green tea, rapamycin, exercise) all either chelate iron or inhibit the pathways iron activates. The narrative arc for PD's content: The medical establishment told you aging is inevitable and cholesterol will kill you. They were wrong on both counts. The real driver is insulin resistance, fueled by belly fat and silent iron accumulation, suppressing your body's cleanup systems while accelerating cellular aging. The fix isn't statins or seed oils. It's resistance training, brief intense exercise, fasting, and managing your iron. Every study points to the same conclusion: aging is a lifestyle disease, not a birthday disease.

On the morning of October 21, 2026, an EF1 tornado moved through the Bradshaw Mountains, crossing Spruce Mountain and over Walker Road, causing many trees to be uprooted and snapped. More information here: mesonet.agron.iastate.edu/wx… #azwx

.@RyanSerhant told me the wealthiest people talk like optimists and prepare like pessimists. "They’re always thinking about what could go wrong internally while planning publicly where everything’s going to go right." It’s a healthy fear. They’re “always preparing for what could go wrong so that in the moment that something goes wrong, they can be opportunistic.” They don’t just prepare to survive the worst. They prepare to profit from it.
