I think I'll stick to neither watching nor listening to it.
As for the weight question: I wonder if weight plays any (significant) role in the likelihood for injuries like that?
Personally I think I would expect the higher weights to be more susceptible to it.
You're absolutely right. The resistability of Bones (and everything) is determined by its cross section area, which is a measurement that's determined by two dimensions. Weight however, is determined by three dimensions. Thus, the ratio from cross section area of the bones to the weight gets further apart the bigger a body gets (assuming the proportions are the same) making it all the more fragile, in relation to its weight.
If you didn't get what i mean, think of this:
Assume that a dice of the measurements 1m/1m/1m weighs 100kg.
Therefore, the bottom area of that dice has to resist a weight loading of 100kg/sqm.
Another dice, has the measurements 2m/2m/2m. Since 2*2*2=8, this dice weighs 800kg. The thing is though, that the bottom area of this dice is only 4sqm - which is why the relative weightloading is twice as high, namely 200kg/sqm.
For this reason, cats (and other small animals) can fall from very high without hurting themselves, while an elephant would break its legs from 1m of falling height or so.
This so called "square cube law" is also the reason why smaller powerlifters can be stronger in relation to their bodyweight than bigger powerlifters.
It's the same reason why some bugs and ants can lift up to 1000 times+ their bodyweight.
It's also the reason why the babies of cold blooded animals are (way) smaller in comparison to their adult size and also why they can afford to already have the same proportions as hatchlings. (E.g. crocodiles).
Mammals on the other hand, always need to sustain a certain temperature to survive, and since the ratio of volume to surface area gets worse in terms of keeping warmth the smaller a body gets, mammalian babies are:
a) rather big as babies, compared to their cold blooded counterparts,
b) in their proportions closer to a ball (short limbs, rounder, thicker bodies) as a ball has the least surface area of all geometrical bodies, enabling it to hold warmth the easiest.
