I've been waiting for this comment to come along. Not everyone is as tough as we like to think we are. I know I'm not. The first real fist fight I was in, I was getting jumped by two guys way smaller than me who were lit on something and just looking for trouble. While they were wailing on my face, I was trying to talk to them the whole time. It never even really occurred to me that I should have been the one stomping heads into the sidewalk and not the other way around. For months after that, I became pretty physically aggressive towards people and did things that I probably shouldn't have. Even now, I train for defensive pistol, but the mind set isn't ever really there, as I do it just because I like it. I like that what I perceive as fun, can also be a survival skill if it ever comes to it, and while my mind may still be in shock at the developing situation, my body may be able to react in a way that saves my life.
All that being said, I think of my mother-in-law, and a majority of older women in my life, and can't imagine anything that they would have realistically done. I think this is a question that can be asked inside our heads, and used to help keep our focus sharp, but to ask it out loud is on the same level as asking a rape victim about what she was wearing that day.
