I wish mark the best. Pretty odd to see all that just from a chest X-ray. I have no idea how much Mark is into alternative/herbal self treatments/research regarding our disease, but it really does help. We all degrade, but i'm sure dealing with several toddlers all at once can't be a good thing for his overall health (though he achieved his goal of being a dad). The lack of sleep alone can compound small things into being big things, but that's the trade off for being a generally healthy CF male being able to have children. I know absolute jack about his baseline, but it's never too late to raise that baseline due to other avenues. Tell him I said get better.
