The idea of being attacked by a larger, stronger person worries both men and women.  Many - especially women - fear that fighting back will only make things worse.

One of the fundamental concepts of Personal Defense is using one's strengths against an attacker's weaknesses.  When I was in high school, I had a friend named Lam.  Lam was from Vietnam, but his paternal grandparents were from Hong Kong, and he lived with them for a number of years while trying to secure passage to America.  Lam's grandfather taught him kung-fu, just as every chop-sockey movie ever made would lead you to expect.
