Do you believe this is a good thing to teach your kids?

[Honest Mommy]

My husband was in the Army for 3 years and has taught me unarmed combat and self defense for my safety. We plan on starting to training our children in self defense and UAC (unarmed combat) when they reach the age of 5 for their safety and keep up with it as a form of exercise, self discipline and family time. I think it's important that all children have some form of training in self defense so that if they are ever attacked they know what to do and how to react in that type of situation, especially if a stranger was trying to abduct them. Granted we also believe in teaching them not to talk to strangers and not to get into a car with a stranger, but you understand our drift with teaching self defense. What are some thoughts on this from other parents?
