"If everyone can do it, so can I"
There's a line I don't agree with. You do it because it's necessary, and because you personally believe it's necessary. Not because everyone else is.
Keeping morale up really is that important, though. It's very easy to unconsciously breath less while depressed, and that's fatal when your respiratory system is already flagging. I'm pretty skeptical about the way drug treatments are introduced, but the logic sounds about right at least.
