Step Forth, Old Man and Woman

Who are they?  That 92-year-old man and the 91-year-old woman are who.  Where they are I don't know, but they have a place in medical history.  The 91-year-old woman had outlived her Stage 4 cancer diagnosis for 22 years, and the 92-year-old-man more recently underwent a successful total knee transplant.  I think younger patients would probably be hearing of successful treatment of patients in their 50's and 60's, but when you get to be OUR age, success stories must be appropriately advanced.
