Honestly these "security" questions are actually easy to answer. You should just make these things up. For example, "What was your first car?" Butterscotch.
I completely agree. They're very dangerous.
Unfortunately those who are inclined to forget passwords find them useful, since its an easy question you can answer.
Of course, most people who know you even remotely can often answer them too. Yet because they are called Security Questions, people just assume they're very safe.
Choosing unrelated answers to them, like a backup password is a good idea, so long as you can remember them when you're given an unrelated cue.
