Why Does Time Slow Down Near Heavy Objects | Feynman Makes It Simple

I don't think I've ever had time dilation explained to me this clearly. He starts with a story about his dad at a barbershop and a simple question — does time go the same speed everywhere? — and by the end you understand why your feet are literally aging slower than your head right now. The falling man thought experiment, Pound and Rebka measuring time differences across a 22-meter building, the GPS being off by 11 kilometers a day without Einstein's corrections — every single piece builds on the last one. And when he gets to the part about spacetime not just bending space but bending time, and that the bending IS gravity, something just clicks. I've watched dozens of videos about general relativity and this is the first time it actually made sense to me.
