A 16-year-old teenager named David Cripe, suddenly died in his classroom. Two hours before, he was drinking one bottle of softdrink, one coffee latte and an energy drink. The county coroner said in his judgment that the student died because of too much caffeine in a short period of time. A normal person can drink up to four cups of coffee in a day, taken on different times. The teen’s father said that this can be a good lesson for everyone about drinking caffeinated drinks in moderation.
