+## Intent
+Securing variables global to a thread, i.e. class variables of the Runnable object, 
+against being spoiled by other threads using the same instance of the Runnable object
+
+![alt text](./etc/tls.png "Thread Local Storage")
+
+## Applicability
+Use the Thread Local Storage in any of the following situations
+
+* when you use class variables in your Runnable Object that are not read-only
