I have thought about that a lot. What's also interesting is various languages and translations. Like if there were a language from some distant place that didn't have the word "should" in it because in their society one would ever use the word should, one either does a thing or does not, there is no "should."

I have also thought that if people had not developed language to communicate perhaps instead they would have developed the ability to communicate telepathically, imagine the possibilities of developing a whole different part of the brain. What if we hadn't invented planes, trains and automobiles? Is it possible that we could astral travel to say "hi" to a friend, like an astral skype? Could we maybe teleport or "apparate" to get around? Imagine the social ramifications of people being able to do that?!

I could go on and on, these things are fun to consider.
