    That’s a little over-simplified. It blocks the sensation of being tired and also has several significant mental effects (including improved reaction time, wakefulness, and hand-eye coordination), as well as physical effects (including increasing basal metabolic rate and improving athletic performance under both aerobic and anaerobic conditions).
