What if the secret to feeling younger wasn’t in pills or surgery — but in sweating? Tech millionaire Bryan Johnson, known for his quest to “reverse aging,” says he’s reached a new milestone: cutting 85% of microplastics from his body.

At 48, the biohacker has spent years testing extreme methods to slow time itself. But this one, he says, was surprisingly simple. “I eliminated 85% of microplastics from my ejaculate,” he revealed online — showing sharp drops in both blood and reproductive samples over a single year. Scientists say these invisible plastic particles, found in nearly everything we eat or drink, can cause inflammation, infertility, and lower testosterone.

So how did he do it? Not through million-dollar machines, but through sweating — daily 20-minute sauna sessions, ditching plastic food containers, and drinking purified water from a reverse osmosis system. “The body can heal if you give it the right environment,” he said.

It’s an unsettling thought: if even billionaires are fighting hidden plastics inside their bodies, what chance do the rest of us have? Yet Johnson’s results leave one haunting question — how much of what we consume is quietly changing us from within?
