Hi, I know that technically the heart is in the middle but it feels it's on the left hand side cos it pumps harder there. However i heard that in some cases the heart can shift a little to the right hand side. Is that true ?

What is the annual ratio of human beings born physically as real hermaphrodites? Anybody know and have a cite to back it up? (hypothetical example: 10 in 250,000)

This is genuine scientific medical question, so please treat it as such. I am not interested in reading anything about sex-change operations, transsexuals, cross-dressers, or GLBT.

I mean if you're a SERIOUS atheist, of the John Gray / Richard Dawkins school. If you've rid yourself of not only the belief in a deity, but of all the other hangovers of faith (the essential nobility of Man, the concept of the soul, eternal life, the myth of human progress, the anthropocentric view of the universe, etc) then does the awareness that you are essentially just a group of interdependent biological systems working together to propagate genetic material, and the knowledge that, when those systems stop functioning, your ability to experience consciousness and sensation will simply end, mean that you have no longer have anything to fear from the end of your life?
