This is an old thread from years back and mentioned a study that had been going on for a few years.

Now - I'm not a Doc but I have put a thinking cap on a time or three.

Sampling of enlistees, sampling of Airborne volunteers, sampling of SFAS vols and grads and at the very end sampling of the SFQC grads.

That would answer the "Big" question.

Looks as if somebody has got on the Federal Grant Gravy Train and will ride it for all they got.
