Training begins with education. There is a topic in this page of information I'd have rathered was put some where else. If your mature enough to deal with the subject it is valubale. The vast majority has to do with the history of this countries self defense laws for it's citizens. You will not be able to read it quickly and starting it with the understanding that it can and most likely will take years is best.
A friends dad died recently who was well into his 90's, he never stopped educating himself. On his last trip to a care facility a few days before his death my friend told me he was checking thimgs out. A facinating man. Respect your mother and father, you'll live longer.
