I've always liked walking; that's one of my favorite things to do, and I try to walk every day. [In Washington, D.C.] I can't walk outside, but we have the treadmill. And I walked eight miles at the ranch last weekend. Now I also lift weights, which is also great for bone strength. [Mrs. Bush mimes a biceps curl and laughs.] I'm very, very strong, actually. - Laura Bush
