 ## Intent
-Securing variables global to a thread, i.e. class variables if a Callable object, 
-against being spoiled by other threads using the same instance of the Callable object
+Securing variables global to a thread against being spoiled by other threads. That is needed if you use class variables or static variables in your Callable object or Runnable object that are not read-only.
 
 ![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 Callable Object that are not read-only and you use the same Callable instance in more than one thread running in parallel
-* when you use static variables in your Callable Object that are not read-only and more than one instances of the Callable may run in parallel threads.
+* when you use class variables in your Callable / Runnalbe object that are not read-only and you use the same Callable instance in more than one thread running in parallel
+* when you use static variables in your Callable / Runnable object that are not read-only and more than one instances of the Callable / Runnalbe may run in parallel threads.
