Your habits are writing your lifespan

How long you live isn't luck. It's the slow compounding of how you move, eat, sleep, recover, and what you avoid. We read those signals together and weight them the way long-term research does, then turn them into your estimated lifespan and the trajectory you're actually on. Early enough to change it.
