wisdom (also)
A recent dental x-ray revealed that I am one of the one-in-a-billion people who have never had top wisdom teeth.
This either means that I'm higher on the evolutionary scale than the average one billion, or half as wise.

Also, it seems that people generally have an easier time expressing and explaining what they don't like rather than explaining or expressing what it is that they do like.

Also, yesterday I found out randomly that the suit I brought against my former (& horrendous) employer a few years ago via the Department of Labor (which I won, and I also won their 2 subsequent appeals) resulted in the IRS forcing them to change their ways. Fucking awesome. One measly example of it working to use the system to promote positive change. Hurrah!
