The LD50 of caffeine for my cat is approximately ten Monster Energy drinks?To an untrained mind, that simultaneously seems like a lot and not much at all. I guess given my cat is 1/10th my weight, that’s like me having 100, which feels like it <i>should</i> kill me.<p>Holy crap. A Dunkin Donuts Large Ice Coffee is 396mg of caffeine. That’s insane. That’s 4.5 Red Bulls.<p>I originally felt a wee bit dismissive of the article’s thesis. But wow, we are absolutely cranking up the caffeine content. I remember Jolt or Bawls or other drinks in high school being edgy because they had “twice the caffeine” (about 80mg for 355ml can).<p>But now we’ve got 400mg in a single beverage.<p>Is this a feedback loop? We keep increasing caffeine content because we need more for our beverages to have the desired effect for customers?
