Aging Biology Fundamentals

Chronic activation of this nutrient sensor disrupts cellular cleanup and accelerates aging.

Cells stop talking clearly to each other as they age, turning local damage into body-wide decline.

Shorter telomeres predict faster aging and earlier disease, but lifestyle factors can slow the loss.

Three separate mechanisms drive NAD+ decline, each worsening the others with age.

Five molecular pathways drive age-related inflammation, but diet offers the strongest brake.

Biological age measures how fast aging is happening now, not how old you are on paper.

Five intertwined mechanisms explain why aging cells can't keep their powerhouses running.
