Talk:Bloodbending/@comment-4575960-20111106181307

Hmm..... there is something that always confused me about blood bending. Namely why manipulation of the body is so limited to water. The body's made up of 70% water, I get that, but I want to know why, say for example, an earth bender couldn't manipulate the calcium salts in a persons bones (or are salts not considered to be part of earth). It doesn't' have to be for attacking either, this could also be used for healing and repair (something else that for some reason only waterbenders are only able to do).
