Let me start off by saying I am not so much permanently disabled but that I have some limitations right now that I hope I will be able to overcome. Due to a knee injury I cannot run and this leaves me feeling somewhat vulnerable. We are often told in MA to distract or hurt an assailant enough to 'get away'. My fear now is that even if I manage to keep my head and get a good strike in I will not be able to escape. I have never felt so vulnerable in my life. If I were to be confronted by someone I wouldn't be able to outrun even the most out-of-shape attacker. I live in a fairly safe city but I have been feeling rather intimidated recently and I was wondering how those of you who have similar limitations deal with A)the physical reality of not being able to run and B)the mental aspect of feeling unsafe when you are out in public. Thanks in advance for your comments!
