Yes, I vaguely remember hearing something about how my great-grandfather might have felt sort of bad about not being able to serve in the U.S. military, but after all he was a 42-year-old minister with seven children in 1917, during WWI, when all males ages 18-59 had to fill out a draft card whether or not they would actually be selected to fight in the war. That duty was more for the younger men with fewer complications, one might easily imagine.
