It is well documented that President of the United States may very well be the most stressful job in the world. You need only look at the pictures before and after a presidency. A young, vibrant, energetic candidate becomes tired, ragged, and haggard after just 4 years.
So what will our next president look like after 4 years? The folks at PopPhoto have attempted to give us an idea. They altered a photo of each remaining candidate to show us how they may look in 4 years. The results are dramatic.
