How Did Ancient Humans Survive Without Salt?

Try going one day without salt. Not just the shaker. All of it. Now imagine living thousands of years ago, with no salt on the table at all. Your body still needed it to survive. So how did your ancestors get enough? In this video, you'll meet the Yanomami of the Amazon, who live on almost no salt, step inside a dark cave where elephants scrape the walls for minerals, and discover the hidden "salt saver" working inside your own body. By the end, you'll see why something once so hard to find is now one of the easiest things to get, and what that means for you. If this changed how you see your next salty snack, hit like, tell us in the comments if you could last one day without salt, and subscribe for more stories about the ancient instincts behind modern life.
