I have never seen a woman crack her fingers! I guess they just aren't as blunt about it.Ladies do this too so do not let it fool you into thinking only men do it. Get some documentation from a doctor and present it to him. I can tell you first hand its a hard habit to break, I am still working on it.
My wife does it all the time. I know this habit is difficult to break, I just told her not to do it so often. Well, at least she doesn't do it in church.I have never seen a woman crack her fingers! I guess they just aren't as blunt about it.
