Have you noticed a pattern with many ads (ok, this wasn't a 'proper' ad) where they begin by asking a question?
Posting a question (in this case, a rhetorical one) to your readers is a great way of beginning your copy, there's no doubt.
Questions generate thought processes within our minds that force us to use our imagination.
There's one caveat with using questions. You need to ask a question that doesn't invite a reply of who cares!.
If you're going to use a question as an opening sentence, then make sure it's relevant to your reader, and always ensure that it's followed by a strong value proposition.
