Anyone want to volunteer for a lung scan? It's not invasive at all, basically you just sit in a chair in front of a screen and breathe normally for a minute, then go for a run on a treadmill and do it again. I won't attach your name to the results, I just need some more data to look at variation in oxygen absorption efficiency. As a bonus, you can pat my dog.
