Paying it forward

My oldest son was crushed by a tractor. The bucket servered arteries behind his knee if four places. Doctors where able to save his leg through seven surgeries. During his longest (13 hour) surgery, he was given 32 units of blood and blood products, over the next 10 days he was treated with at least 10 more units. I have committed to donate every chance, I get. It will take me almost four years to give back what others donated for him. Thanks to all who donate blood.
