It wasn't meant to be dumb. What can a woman do to defend herself from being brutally rammed by a man?
your question reminds me of an Argyll & sutherland Highlander Sgt who although he was not asking about self defence on a woman , asked me this question in a pub what would you do first. I said head butt him as i am fast with my head, he said no spit in his eyes. simple but effective.
also the most simple stuff is the best such as when i asked a similar question to a Wado ryu Sensei, he thrust one finger into my lower throat just above the collar bone and i choked. It´s very dangerous.
