[Cooker]

Why would an atheist care more than a spiritual person about what happens to his body after death? I know I don't care one bit what happens to mine and have specifically told my wife to spend as little money as possible to get rid of it. If she sold it to necrophiliacs I wouldn't care. Once I am dead what do I care about my body, I won't care about anything.

An atheist might even take certain things as more valuable than there own lives. For instance, if I am a strong believer in natural selection and I was offered the opportunity to have 100 children that grow to adulthood, but be terminated immediately after the conceptions (but the growth to adulthood is guaranteed), I might accept that.
