Thoughts

This started out as a Facebook status. It began as a legitimate question and then morphed. I don't understand why, but I feel like posting it:

Do you think people who are about the same age typically know about the same number of people? Of course there are different levels of knowing people, but I wonder if any of us really knows a lot more people than anyone else. How many people do you think we can meet and remember? Why is it so difficult for some people to remember names or faces? Why am I still awake? Why am I writing this? Am I really going to post this? Probably not. But maybe. Welcome to my brain. I'm tired.
