Lucy Lawless, Star Of 'Spartacus: Vengeance,' Answers Six Science Questions

Huffinton Post - Science 8 February 2012

As part of HuffPost Science's new Celebs Talk Science series, we challenged Lucy Lawless, star of "Spartacus: Vengeance" and best known for her role in "Xena: Warrior Princess," to answer six quirky science questions.

1. If you could reengineer the human body, what is one thing you would change?

I would have a dual respiration system so that we could convert our breathing from oxygen to carbon dioxide to carbon dioxide to oxygen and back again. Of course we'd be excreting coal dust, which would be murder on the soft furnishings. Not sure what to do about that. Black sheets?

5. If time travel were possible, what day/era would you want to get to? Why? What would you do? Whom would you meet?

I would go forward and ask my great grandchildren what they wish we'd done better. Though I'm afraid I already know the answer to that. We have to move on climate change NOW. Or our grandchildren will damn us for our sheer laziness and cruelty.
