I'm 41 now and the right knee has got a bit of a twinge in it. I get about the stage a little less now.
My mom is in the navy and my dad works for the army, but I never called them 'sir' or 'ma'am' or anything like that, and we never really moved around a lot because both my parents were stationed in D.C.
