Diabetic War Horse star Jeremy Irvine loaned his body to science for medical research on an artificial pancreas.
The British actor, who suffers from Type 1 Diabetes, was approached by scientists testing out equipment developed to work in tandem with a portable insulin pump for those struggling to control their blood sugar.
Irvine reveals he jumped at the chance to help out and immediately took part in the clinical research trials at the University of Cambridge's Addenbrooke’s Hospital in England.
He tells New York Magazine, "I've been diabetic since I was six, and the medical research team had done so much for me, it was a no-brainer to give back. I wouldn't say I was partly responsible for kids living longer lives, though. That would be very arrogant of me. There were brilliant people working every day on this, so I'm only a tiny, tiny part of it."
