COLONEL HARLAND SANDERS
LAURA INGALLS WILDER
Ernestine Shepherd didn't start exercising until she was 56 -- she was even allowed to sit out of gym classes as a child because of an injury she got in a car crash. But that didn't stop this former school secretary from hitting the weights. Eventually, she started training for a bodybuilding competition at age 71. She won, and was eventually awarded the Guinness World Record for being the oldest competitive female body builder in the world.
