    They are using the median lethal dose, or LD50, for this video, but many people can experience severe problems with coffee, or energy drinks, way below that level.

And, sadly, quite a few people have died after consuming too many energy drinks.

    It’s really hard to OD on caffeine, but people with heart problems can die from an accelerated heart rate or irregular heart rhythm, even after only a few cups.

    Caffeine is produced in plants to discourage foraging insects and animals. It’s essentially a pesticide.
