SOS-System
What is the SOS-System ?
The SOS-System stands for Survival On the Street System and has been developed by Christiaan Dekker.
The SOS-System is for everyone who wants to be able to defend himself/herself in dangerous situations or emergencies. Keep in mind that an emergency is a situation where you want to yell SOS or in other words HELP!
