How dangerous is the world we live in?  Is it really full of criminals ready and waiting to do god knows what to you?

To be honest, I highly doubt it.

I have heard all kinds of studies:  some that say 3 of 5 people will be victims of a violent crime and even that Iraq is safer than downtown areas of the U.S.

Just watch where this information comes from.  It usually comes from sites selling self defense products. 

Self defense is important, don't get me wrong, but it isn't something that you have to have to be able to walk down the streets.  I do believe that you should learn some self defense, but don't spend a lifetime doing it.

The truth is:  The world is not full of killers at every corner stalking you.  Sure crime rates have risen over the last 30years,  but so has the population.  crime rates to population percentages have not changed very much.  Meaning, you are just as likely to be a victim today as you were 30 years ago.
