Having 1 healthy, fully function lung is completely different from having 2 lungs with one functioning at 50%. The human body will adapt to having 1 lung or 1 kidney and function just fine. When an organ is sick in the body the entire body is fighting and that's what saps energy.
I'm not Catholic and don't have a dog is the fight but only time will tell how remarkable this Pope will be. He has an opportunity to be more relevant and right many wrongs.
Reports that the Pope only has one lung are not true.
He had a PORTION of one lung removed decades ago as a young man.
And yes, having it removed early in life, as with many other organs, is NOT the same as having one removed much later.
The remaining organ and portions of organ can expand and functioning capacity stay pretty normal.

Pope's partial lung doesn't slow him down, Vatican says
Cardinal Jorge Bergoglio of Argentina was elected to lead the Catholic Church following the resignation of Pope Benedict XVI.

Vatican officials now say that the new
Pope Francis lost just part of a lung to disease as a young man, and that the injury has never affected his work.
Cardinal Jorge Mario Bergoglio of Buenos Aires had a pulmonary illness some 40 years ago during which part of one lung was removed, according to Fr. Frederico Lombardi, director of the Holy See Press Office.
"This has never been an obstacle either in his rhythm or for his work, his life, or his pastoral care, as demonstrated by leading a diocese that requires such dedication as that of Buenos Aires," Lombardi said in a press release issued by the Vatican on Thursday.
Still, doctors said that any significant lung loss likely hadn't limited the 76-year-old pontiff's energy or actions in the past -- and shouldn't stop him in the future.
Pope Francis appears to be fit and lean and should have lung capacity that is nearly normal, said Dr. Zab Mosenifar, a lung expert at Cedars Sinai Medical Center in Los Angeles.
"It just didn't faze me," Mosenifar said.
The new pope likely lost part of his lung decades ago, at a time when severe fungal infections or pneumonia were treated with surgery because antibiotics weren't widely available. But his existing lung likely grew and expanded to near-normal capacity within a year or two, said Mosenifar, who is co-medical director of the Women's Guild Lung Institute.
Human lungs have excess capacity, which is why doctors typically use only one lung in transplants. There are likely 30,000 to 40,000 transplant patients in the U.S. living with one lung, and thousands more who lost an entire lung or part of a lung to disease or trauma, Mosenifar said.
Many single-lung patients go on to have not only normal lives, but active ones, said Dr. Edward Salerno, a pulmonologist with Hartford Hospital in Hartford, Conn.
"They can exercise and not feel any dysfunction," he said.
