James Harrison, an Australian blood donor, was nicknamed the "Man with the Golden Arm."

 His blood contained the rare antibody necessary to make a life-saving medication: anti-D. 

Anti-D injections were given to pregnant mothers whose blood was incompatible with their unborn baby's. 

James donated over 1,000 times. 

What he could survive without saved over 2 million lives.

 What we find important to keep in our lives changes over time. 

Things break, hobbies age and dreams evolve. You learn from experience to narrow down what really matters.

 And who you want standing by your side at all times.

 And once you do, you hold on as tightly as you can.
