Two developers, same Claude Code. One automates their entire workflow. The other types the same context prompt for the hundredth time. The difference is .claude/ configuration — and this is the complete map of every setting that matters.

Autophagy is your cell's recycling crew. But past a critical damage threshold, it switches allegiance — protecting senescent cells instead of clearing them. A 2026 review proposes a threshold model and maps exactly where the betrayal happens.

Iron is essential. Under the wrong conditions it ignites a molecular chain reaction inside your cells that looks exactly like rust. Scientists only named this process — ferroptosis — in 2012. It may be one of the central engines of aging.

38 trillion gut bacteria outnumber your human cells. A 2025 Nature Aging study identifies a gut-derived metabolite actively corroding your blood vessels. Your microbiome is not a passenger in aging — new research shows it is the driver.

> TL;DR: You produce over 200 billion blood cells every day. But the stem cells responsible for that production are slowly going on strike. A wave of landma
