Humans have a suite of abilities that allow us to learn things very quickly, and not always by having to experience them ourselves directly. So we can learn from the experiences of other people, actually, just by watching them. Your brain is bathed in information that it's constantly taking in. And your brain kind of wires itself to the world that it encounters. It does this really quickly when you're little, and it does it slower when you're grown up,. but it's still doing it when you're growing up. If you read books, see movies, talk to people over coffee, their experiences, to some ant, become your experiences.
