Bryan Johnson spent six months achieving what he calls "perfect" sleep and argues it's a superpower anyone can reach. He compares the feat to breaking the four-minute mile, saying that once someone proves it's possible, it becomes a tangible goal for everyone else.
Previously in my life, I would go to sleep and I would have no idea what was impacting my quality sleep or not. Where are you at now? I completed six months of perfect sleep and what I was trying to do was something akin to like a 4 minute mile someone climbing Everest. It was basically a demonstration of human ability that people didn't think was possible. And then once one person demonstrates it, it opens it up for everyone else because if I can do it, everyone else knows they can do it too reliable, high quality sleep is achievable.
