The wolves in Skyrim are quite easy to pick up and move around while the humans are sometimes quite heavy even with no armor on. I just finished burrying my dog and he was about the size of one of the Skyrim wolves, he was very heavy, almost too much for me to carry! (maybe I'm not as beefy as Dovahkiin, but who cares.)
Also the heads of my decapitated enemies are heavier than the body itself. . . would it have been that to make the heads/animals be the correct weight? I know that the heads are heavy to make them roll more realisticly, but couldn't they make them lighter when you pick them up and go back to the regular weight when you droped it? Yes, this could be called a hating thread but I think it a good point to bring up.

Try picking up a bunny haha.

There are two preset values for how heavy a dead body is, one for NPCs and one for critters, and they apply regardless of how much of said body is actually present. That this results in severed heads weighing as much as the entire body is a result of the code that uses this function considering the entire corpse as a single entity regardless of the number of pieces it's currently in, and applying the proper amount of 'drag' accordingly.

Another side effect of their being globally applied is that a bear corpse weighs less than a human one, while a bunny corpse is stupidly heavy for something so small (but still lighter than a human body) and a dragon corpse is basically weightless for its size. Whoever implemented the critter number forgot to also code in a scalar to compensate for the huge variance in sizes thereof, which was rather careless of them.

Sorry for your loss.

Or, they realized that comparing weight on corpses is a rare thing to do.......

Me, if I can move it, then it does not matter what it weighs as it is not going in my inventory.

let me ask you a serious question: why do ANY of you care about this rofl..? this is the biggest nit picking i've ever seen..who..cares..
