It's interesting that some American's state that they have the ability to care less to indicate that they find something unteresting... where as other Americans and British people, state that it wouldn't be possible for them to have any less interest in the subject...
I find it very interesting as the former implies the speaker still has interest in the subject... the latter states that the speaker is currently at the lowest level of their interest in the subject and thus seems more semantically correct... how do others here feel?
