Renaming post titles in a blog, does it changes the original link?

In blogger, I am considering renaming most of my post titles. Would it change the original link?


Would it affect search engine results?





Example:


Post title: "drinking water"


http://myblog.blogspot.com/2008/06/drink...





renaming to "drinking a glass of water"





Does the link changes as well? to something like:


http://myblog.blogspot.com/2008/06/drink...





All I want to know is that if Ive had posts for a few months, driving steady traffic and stuff... if it's ok to rename them





Thanks!

yes it would, you would have to change the link as you are being more specific, some one else could have a blog "drinking a bottle of water"
