Inside every one of your cells live tiny ancient bacteria called mitochondria. When they fail, and they fail decades before you feel sick, they drive cancer, Alzheimer's, heart disease and diabetes. Here's how they fail, and how to rebuild them without drugs.

Chapters
00:00 Introduction
00:33 What mitochondria actually are
02:01 The four ways mitochondria fail
03:56 The diseases this explains
05:34 How to rebuild your mitochondria
07:35 The bottom line

Key takeaways
Mitochondria decide whether a cell lives or dies, control inflammation, sense nutrients and regulate hormones.
They fail in four ways: oxidative damage, DNA mutations, dysfunction, and failed cleanup (mitophagy).
Broken mitochondria release DNA fragments that trigger the cGAS-STING pathway and chronic low-grade inflammation.
What rebuilds them: Zone 2 cardio, high-intensity intervals, time-restricted eating, cold and heat, good sleep, and avoiding what poisons them.
