Please excuse my ignorance to this topic but, what are the symptoms of a HPFP failure?

What is the biggest cause of this?
How or Why does it happen?
How do I know when it happens?

Most of you who have experienced HPFP failure, are you pushing your cars all the time or can this also happen to very conservative drivers as well?

Thanks in advance for your responses.
