The Toughest Route to Becoming a Doctor

... occurs after a liver, heart, lung, and kidney transplant:

Allison John, 32, made medical history in 2006 after she received her fourth organ transplant -- a kidney from her father, 61-year-old David John, to add to her previous heart, lung and liver transplants.

A life plagued by illness and frequent hospital visits has not deterred John from her dream of becoming a doctor, however. After 14 years of interrupted study, she finally received her medical degree from Cardiff University last month, according to the U.K. press.

Wow.
