SOUNDS LIKE CARL IS MAKING GOOD PROGRESS

"Recuperation seems to be progressing nicely.  I begin physical therapy today.  13 weeks.

I have been walking.  Distances are short.  Breathing returns to normal faster than I can remember.  I must still work on lung volume.

The only glitch has been drawing about a liter of fluid from my left lung.  Hope that's the only time.

I'm feeling better and better."

I think I caught a glimpse of Carl in this video.
