There is so much information floating around out there that even the Internet hasn't been able to capture it all. No matter how long we live... how much we read, research, listen, and learn ... we are never going to "know it all."
There will always be more to find out about life, the world, and ourselves. There will always be fun facts we have yet to hear and interesting bits of trivia left for us to discover. Our "seasoned" years can be a great time for exploration and learning.
