Can I just use it 'til I need glasses?

Back in March, there were reports that linked Viagra use to blindness -- under certain health circumstances.

Now, according to this story, the number of those afflicted is increasing.

Surely there is some humor in this. Could this be Nature's way of saying "Enough already"?

Given the choice between seeing or doing it blind for the rest of my life, I'll vote for sight -- every time.
