             Sometimes it is unclear how a regular expression can be rewritten to
             avoid the problem. In such cases, it often suffices to limit the

+            length of the input string. For instance, the following 
             regular expression is used to match numbers, and on some non-number 
             inputs it can have quadratic time complexity:

             It is not immediately obvious how to rewrite this regular expression 
-            to avoid the problem. However, it might be fine to limit the length
+            to avoid the problem. However, you can mitigate performance issues by limiting the length
             to 1000 characters, which will always finish in a reasonable amount
             of time.
