Oh no, it broke. An open letter to disease. Dear disease, why do you always put yourself at the center of human history? Most of you are just tiny little single-celled organisms, but you're so self-important and self-involved that you're always interfering with us. Admittedly, sometimes you work for the good guys, but usually you don't. It seems like even though you're constantly interfering with human history, you don't even care about it. I hate when people, and also microbes, are super self-involved.
