Jeanne:
I suffer from emphysema. Fortunately, it is not severe enough to make me have oxygen. But, I participate with the Airheads support group (indeed, I'm the VP) many of whom do use oxygen, some 24/7. Almost all of them comment when the humidity makes it more difficult for them.
The positive thing is, I think, that all these folks are active, active, active - like most TV people! Early morning humidity may be harder for them, so maybe they schedule tee times nearer to noon, and avoid those 7:28am times!
I don't think that the humidity is really any worse here than most anywhere else, save Arizona and the high elevations around Denver. I'm willing to bet that your upstate NY (assumed) humidity is no worse than ours here.
Whatever, good luck. And, come meet with the Airheads when you're in TV. We have lots of fun, and you'll learn all kinds of new stuff!
