Irony won't save you from anything; humour doesn't do anything at all. You can look at life ironically for years, maybe decades; there are people who seem to go through most of their lives seeing the funny side, but in the end, life always breaks your heart. Doesn't matter how brave you are, or how reserved, or how much you've developed a sense of humour, you still end up with your heart broken. That's when you stop laughing.
