We have failed to protect science against speculative extensions of nature continuing to assign physical and mathematical properties to hypothetical entities beyond what is observable in nature.
Sometimes I make very selfish choices like I did 'Once Upon A Time' for my inner 8-year-old and my hypothetical future child. I've done some movies because I would regret them if I didn't but other projects I've done because they've scared me or if I felt I needed to do a big romantic comedy to help me professionally.
Of present fame think little and of future less the praises that we receive after we are buried like the flowers that are strewed over our grave may be gratifying to the living but they are nothing to the dead.
