Caffeine is an illegal stimulant?
This wasn't very close to the fuzzy line. A runner from Surinam had the equivalent of 5 gallons of coffee, in caffeine, in her system. So she was disqualified. I didn't know they were sticklers about caffeine. I wonder if people can be hypnotized (see other story) to perfom better and, if so, whether that would be permitted or detectable.
Subtlety is not one of my strengths
