Yeah . . . this seems like a pretty accurate look at what unanswered questions are REALLY bothering mankind on a daily basis.  It's not "where did we come from?" or "why are we here?"  Nope . . . it's all about sex and vanity.

Slate.com asked readers to submit THE biggest unanswered question on their minds.  They left it open-ended, so people could submit any question they could think of.  And these three questions got the most votes:

#3.)  When did mankind figure out that sex causes babies?

#2.)  Why do we all hate the sound of our voice on a recording?

#1.)  Why do rich and famous women always sunbathe topless?

They've done this survey in the past as well.  Here are some of the top unanswered questions from previous years . . .

--Why are smart people usually ugly?

--Could mankind blow up the moon?

--Why do boys like sticks so much?

--If a Siamese twin commits a murder, does his brother get punished too?

--What's the most disloyal dog breed?

--Why don't we drop medical waste into volcanoes?

--Can a bar of soap get dirty?
