A parent's love their child knows now bounds, and this latest report from The Local explains why. The story involves two parents from Germany who donated one lung each in order to save the life of their son, who suffers from cystic fibrosis.

It started when their son Marius had to be hooked up to a ventilator and a heart-lung machine. The parents waited and waited for a donor, and when one failed to materialize, they decided to intervene and put their own bodies up in order to save the life of their son.
“The transplant was his last chance,” said Dr. Gregor Warnecke, the boy’s supervising doctor. “If we had enough organ donors in Germany, the doctors would not have to resort to living donors,” said the boy’s father, Lars.
Fortunately, both parents were compatible blood types and their lungs were larger than their son’s (this is a necessary prerequisite for donation). The surgery took roughly six hours, and both parents were able to leave the hospital after ten days.

Marius spent an additional 155 days in the hospital, but he can now breathe more easily, thanks to the sacrifice of his parents. Although he still has to take a series of drugs to counter the cystic fibrosis, his prognosis and quality of life have greatly improved.
