5 Reasons Why 2013 was the Best Year in Human History

5 Reasons why 2013 was the best year in human history - a quick summary of an article at http://thinkprogress.org/security/2013/12/11/3036671/2013-certainly-year-human-history/

1. Fewer people are dying young, and more are living longer.
2. Fewer people suffer from extreme poverty, and the world is getting happier.
3. War is becoming rarer and less deadly.
4. Rates of murder and other violent crimes are in free-fall.
5. There’s less racism, sexism, and other forms of discrimination in the world.

While this is a good list, I suspect it's incomplete. What else would you add to it? For example, in 2013 there were probably more scientists working to solve more of the world's problems than during any year in history. Other thoughts?
