"You've got to be willing to take orders. You've got to be willing to live in harsh circumstances. As someone has put it, you've got to be able to miss a meal if it's necessary. And you've got to have a wife that will put up with all these things. My wife has been wonderful. We moved twenty-six times, lived all over the world. When I was away, she was responsible for everything -- for buying houses, for paying the children's tuition, taking them to the hospital, etc., etc. Today, so many of the very young people are getting married, and we have also so many girls in the military. Someone over in the Pentagon told me the other day [when] I asked him what are the main problems now, he says: "Child care and pregnancy." But that wasn't present when I was a young officer."
