I'm confused by that first panel. Is it supposed to say 50 pounds or 50 kilograms? There's quite a difference between the two, if an adult is only 50 pounds then that means they're starving to death AND significantly smaller than the average adult in general. Also, isn't muscle heavier than fat? Meaning as long as the BMI (Body Mass Index) is low, the high weight is actually a good thing?
...Or am I just drastically over-thinking this fictional comic? Still, if someone is 50 lbs and is either not a small child or a little person, then that is frankly alarming.
