Apparently, Pliny the Elder recommended onions as a suppository, believing that 
they were a good cure for hemorrhoids. So that's why they make your eyes water. Foolish me, I've been putting them in food all these years. 
Maybe that's why stereotypical Frenchmen wear strings of onions round their necks to help with the painful consequences of all the cycling they do.
