I've been involved in some SIMULATOR testing where the pilot subjects were fully physiologically 'wired' and then subjected to various critical abnormal and emergency situations, chosen for the most intense sound and motion cues, and difficulty of assessing what was actually occurring, as well as subsequent physical strength requirements during recovery.
Except for verifying an occasional pre-disclosed heart anomaly, the preponderance of pilot actions and
physiological responses were the epitome of the 'right stuff'.
It's a simulator, dude.
Don't rule out that thought, although there may be more ways to do that effect than direct injection.
A waft of perfume perhaps?
You know the joke about Acute Angina.
