The Solomon System.
A gentle answer turns away wrath...
:rotfl: Sure.

The best self defense system is a well-experienced one - which one is irrelevant against the average attacker.
My huge dog helps [a lot]. But if you have naturally good balance and can keep calm under pressure, keep your hands up... then with a little knowledge of anatomy - there's little doubt you'll be in real danger. (Unless against someone armed)
I think krav maga is overrated macho nonsense that you'd never remember or be able to apply properly and that it's the experience of conflict that is actually useful.
So much improvisation goes into a fight that unless it's muscle memory [krav maga could be useful there with ENOUGH training] its natural intelligence, problem-solving, endurance and strength that usually comes out on top.
I think it's unwise to recommend martial arts or a system to someone who just is not capable regardless of experience/knowledge of defending themselves, especially in the face of death.
