I can confirm this.

I got a really hard pneumonia few years ago. It took several days in hospital to find an antiobiotic which actually worked, and I was in pretty bad shape in ER when it finally started to work.

It took 10 weeks to recover back to work, and over a year before lungs were back to normal, confirmed by x-ray.

Pneumonia can be deadly, even for healthy young adult.
