Should asthma be understandable?

Is it mystifying that so much research effort continues to be thrown at a disorder as common as asthma?

Yoga has taught the art of breathing for thousands of years and its philosophy of pranayama makes elegant sense to me.

Then there are the learned institutes of today none of which seem to be able to separate things like allergy and substance sensitivities from what should be far more fundamental - simple breathing.

Graeme Greenup on asthma:

The suspicion that the asthmatic may try too hard to breathe better, but consequently breathe worse, may lead us to some more of the various possible vicious circles in asthma. A few of the more obvious are:
...
We may conclude, then, that the sympathoadrenal system in the asthmatic is constrained ...
asthmatics may simply try too hard and, consequently, not breathe well
...
Stimulus of the 'fight/flight' response, or administration of a sympathomimetic agent, may help the asthmatic to break out of the immediate spasm - but learning to relax from cortically-driven overbreathing would be better.
