the redbull people reps for my area came to my marketing class and talked to us about redbull and what is does, gave us soem redbull. We watched this movie on all of the sponsored athletes and the skiers were like the whole movie, it was great. And he said that drinking two redbulls wont do anything else for you that one redbull wont do. the amount 8.3 ounces, which is what a redbull comes in, is the perfect amount of energy. any more and your body just flushes it out. did you know that steve winterton issponsored by redbull, thats gay. and the reason you cant buy the redbull helmets or clothes or anything is because only paid employees of redbull, or people sponsored by them cant wear it.
