Resolution

My husband and I love talking with each other.  His job allows him to text when he'd like, and I'm able to send him messages and call whenever I need to (or want to, really).
There's only one problem: we generally talk about other people.
It isn't always bad.  But it bothers me that our conversations are so lacking in depth.
We don't constantly talk about other people, but we do it enough that it bothers me.  I want to change it.

Thanks to addiction recovery, I've learned that if you want to rid something rotten out of your life, it helps to replace it with something uplifting and good.

So.
My New Year's Resolution (though I hardly ever make them) is to read one wikipedia article every time I catch myself using other people's lives for conversation fodder.

It's January 5th, and I'm three articles behind.

Hopefully 2013 will be a year filled with better, more uplifting conversations.

Here's where you come in... I need wikipedia recommendations!  What do you love to study/read about?
Wars?
Movies?
Science?
Music?
Health?
Food?

I need three fresh ideas ASAP!
