In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. John G. Cramer — Emeritus Professor of Physics at the University of Washington and author of "How to Live Much Longe...

Your doctor orders a lipid panel every year — but 3 cheap blood tests predict heart disease, diabetes, and even dementia far better than cholesterol, and most doctors never order them.

In 1969, Harvard pathologist Kilmer McCully discovered elevated homocysteine causes arterial damage and heart disease. He was forced out of Harvard. The Framingham Heart Study confirmed him. Then the AHA buried it anyway. CHAPTERS: 00:00 - McCully discovery and suppression 01:20 - Part 1: What homocysteine does to arteries (6 mechanisms) 03:25 - Part 2: The evidence they ignored 03:40 - Every 5 um...

What if an AI could run centuries of aging experiments in a year?

Walking videos are everywhere — "walk 10,000 steps and melt belly fat." The conclusion is right: walking does reduce body fat. But the explanation is completely wrong. Your body compensates for ~80% of exercise calories. The real reason walking transforms metabolic health has almost nothing to do with calories burned. Here's the actual science. CHAPTERS: 0:00 - The walking myth: why...
