Comprehensive questions about drinking Red Bull before physical tests, sports, and competitions: how much to drink, when to drink, how much time in advance, etc.

I worked at Red Bull, and I will tell you the truth: It makes sense that Red Bull is as popular as chocolate before the high school entrance examination and college entrance examination. The experience of these candidates for more than ten years shows that 30 points before the physical test, and after the physical test Drinking Red Bull for 30 minutes can not only replenish energy and improve performance, but also has a psychological suggestion effect due to its exquisite packaging. This is a scientific drink. Many athletes drink Red Bull, just to avoid advertising suspicion and use another container to hold Red Bull. As for the death cases, aside from hearsay, Red Bull already accounts for 50% of the global functional drink market share. Although it is not a monopoly, it has also been slandered by local beverage rumors. You can't fall off the bench and die because the bench is too high. In addition, everything should be done in moderation. If you drink 3000 ml of Erguotou in one hour, you will either die or be disabled. Please don't answer with this stupid knowledge.
