So once more residents of the United States find themselves on a collision course with the Thanksgiving holiday. Some of us make a point of celebrating it, some are obligated and others disregard it as much as possible. Between the traditional turkey gluttony and America's historical mistreatment of Native Americans, there are certainly some good excuses to abstain. Growing up. I didn't really care about the whole gratitude thing to be honest. Today, however, it feels appropriate to think a bit about what's good in life and how little I've done to diverse any of it -- and it looks like science backs me up on that.
