It’s too short.
We, as a species, are making the same mistakes over and over. When I read something written in ancient times it’s remarkably similar to today. They’re complaining about taxes and that their kids don’t understand them etc. If we lived longer (in a healthy state – not body breaks down at 50 and we live to 3,000) I’d like to think we’d be less frantic, more considerate. And I hope that as a species we’d learn a few useful lessons, including how to pass those useful lessons on to the next generation.
