Your Body Can Either Grow or Repair — Not Both, Here’s Why (Ft Renee Fitton)
Why is it that we chase longevity like it’s a number, yet ignore the daily behaviors that are aging us from the inside out?

Renee Fitton — registered dietitian, longevity specialist, and one of the leading voices in fasting-mimicking science (VP at Prolon) — breaks down the biology of renewal… and the psychology that quietly shapes our habits.
