Gotta say, I've been in a group chat with a bunch of Arab POISers and what's nice is that we have two doctors and one medical student. But what's less nice is that they are completely oblivious to what causes POIS or even its general mechanism.
So that's generally why we have such a failure with doctors, and you can't blame them really this disease was only discovered in 2004, it'll need time, and even when it comes to the current investigation there is a high chance of failure; needing a second grant to investigate alternative hypotheses if the current one completely fails.
