The American presidency is known as a difficult job. Men who hold the highest office in America often come out of it with more wrinkles and gray hairs than they had before. They are able to live longer, thanks to the high-pressure job.

In fact, history has shown that 23 out of 34 presidents who died from natural causes have outlived their peers in their age group. This makes perfect sense, as presidents have access top-notch medical care.

So you can decide which president is your favorite, we have combined two images taken at the beginning and the end of their terms. Here are the ages of each president while serving as commander-in-chief.
