I know instantly whether I should

I know instantly whether I should take a role. If my skin tingles as I read the script, then it is absolutely something I must do.

Therefore, if you dream of a society in which truth reigns supreme and myths are ignored, you have little to expect from Homo sapiens. Better try your luck with chimps.
