This review suggests lung resilience in older age depends heavily on background inflammation and repair capacity.
If you ever wondered why pneumonia or severe flu hits older people so much harder, this review lays out the reasons. Aging lungs carry more worn-out cells, more low-grade inflammation, tired mitochondria and a weaker repair crew. That combination makes the thin barrier between air and blood easier to damage and slower to heal. Researchers are now testing treatments aimed at these aging processes rather than just the infection itself.
