Last known continuously serving draftee retires after 42 years of service

Do you think there are others we don't know about?

CW5 Ralph Rigby just retired after 42 years of service after being drafted 1972 at the age of 19. Having joked about moving to Canada when he was drafted, his is an inspiring story of selfless service. He also appears to have quite the sense of humor about it all. I think we can all learn a lot from Mr. Rigby: http://www.army.mil/article/137112/
