Note that many game skeleton RIGS don't even have a neck bone and manage to do the job with only a headbone.
注意:在许多游戏中并没有颈椎骨,只要用一块头骨就能搞定。

Again we are looking for a way to describe the size of a humanoid that does not rely on a specific point like headbone position since it is not consistent from rig to rig.
