Do you ever notice simple things that are wrong in a lot of fantasy books?

For instance, it seems that, in many fantasies, characters are able to hunt, kill, skin, and cook a dinner out of their quarry all in a blink of an eye...when in reality it takes a good while to de-bone an animal, let alone cook the meat into a stew.

Another one that bothers me is how easy characters can ride a horse at full gallop for hours on end, as if the horse never gets tired and the character's ass never hurts!

Any others?
