@SuperTaliaDX @devurandom Building on this, and on what @woozle mentions, I wonder if the reason we *think* there exists an age at which a person's character becomes "fixed" is because, until recently, a person's social *environment* would have already been "fixed" before that. No new exposure to new personalities or opinions or ways of thinking. Nothing new to learn. Nothing to grow from. Except all these "weird kids" running around "trying to turn the world upside-down," who you just ignore because you assume they "just don't get" "how the world works", so you think you don't need to learn from them.
But now, with how much easier it is to interact with people outside of work, or church, or the house you literally live in, you *can* find people--from all over the world, even!--to learn new things from, to continue to become a *better* person, rather than a more stagnant one.
