The most mysterious illustration for erectile dysfunction ever

This Saturday's long tea-time of the soul brought with it an interesting discovery. While surfing aimlessly for a bit, I've stumbled on a strange combination of a picture and a caption:

What would two seemingly uber-healthy male characters have to do with that horrible malady? So I've clicked on the link. Of course.

The headline didn't change inside the link, it's still: Twenty-six percent of young men had erectile dysfunction. Only a rubric name was added: Health News. And the picture presents the same view, only with a better resolution:

The file name of the picture is Twenty-six-percent-of-young-men-had-erectile-dysfunction.jpg.
Instead of, for instance: Two-braves-doing-pushups-in-the-rain.jpg or something in this vein.

However, there is a caption under the picture, it says:

One-in-4 men age 40 and younger have erectile dysfunction. Young men do pushups in the pouring rain next to the Washington Monument on the National Mall in Washington.

If you can establish a link between the first and the second sentences in this caption, you are a much better man/woman than I am.

The article itself, by the way, is about statistical results obtained from 439 Italian men seeking medical help for newly developed erectile dysfunction (emphasis mine).

Well, that's it. I leave the mystery to you, since as I have mentioned, you are a much better man/woman. Oh, and one other thing: from this moment I shall never do pushups in the pouring rain next to the Washington Monument on the National Mall in Washington.

Just in case. And don't even beg me.
