As an oldster compared to many others on this site, or the internet in general, I see many times where people use the incorrect words in an old expression. Many times it's because the reason behind the expression doesn't even exist anymore, like usIng a horse and buggy for transportation (unless you're Amish!).

The main thing about writing, and that I struggle with too, is to use the least number of words possible to get your point across. Often in speaking we use more words but writing is different because it must be read later.
