Well there's no point in asking a dead person because they can't answer back. I would like to sit down with Richard Dawkins for a discussion about the appendix, and I would like to ask him about what his thoughts are regarding its function in the past, present and future.
I don't know but your question did make me think of the fact that some of the early neuroscience experiments were conducted on dead subjects.. they showed or said things to dead subjects to see if there were any differences in how male and female subjects. One such experiment was conducted on dead salmon... hmmm
I'd ask Leonardo DiCaprio what it's like to be him? Rich, famous, talented, attractive sleeps with anyone he wants and I bet he'd break down and tell me "It's a f_cking nightmare, some days I just wanna be normal and have a family and be anonymous, but I can't, I'm trapped." At least that's what I tell myself he'd say, it makes me feel better.
