Here's an inspiring tale of Kelli Lim, a triple amputee who beat the odds to become a doctor:
The Michigan native, 26, does not use a prosthetic arm and manages to perform most medical procedures - including giving injections and taking blood - with one arm. She walks on a pair of prosthetic legs.
"Just having that experience of being someone so sick and how devastating that can be - not just for me but for my family too - gives me a perspective that other people don't necessarily have," Lim said.
