Presidential Diseases

I linked to something similar to this before.

But here is a collection of U.S. Presidents and their health.

For instance, did you know that James Garfield suffered from:

Malarial fever (ague), cold, upset stomach, anal fissure, infected gunshot wound, heart attack or aortic aneurysm (?), blood poisoning, pneumonia.

Not sure what anal fissure is, but I think I'm better off not knowing.
