What are posthumans?

Posthumans are people who have grown stronger or smarter than regular humans, kind of like how a superhero is stronger than an average kid.

Imagine you're playing with your favorite toy robot. It can run really fast and lift heavy blocks, way faster and stronger than you could ever do. Now imagine that one day, you get those same powers! You become like the robot: super strong, or super smart, or both. That's what posthumans are, people who have gone beyond normal human abilities.

Sometimes, posthumans happen because of technology. Like if you wear a special hat that lets you see in the dark or run really fast. Or maybe you take some medicine that makes your brain work faster than usual.

Other times, it's like growing up, but way faster and more powerful. Maybe you learn everything in seconds instead of years, or you can live much longer than anyone else.

So posthumans aren't just people who are bigger or taller. They're people who have become super strong, super smart, or both, and they're ready to take on any challenge!
