My mother used to say, 'You gotta exercise.' She would really pound on me to exercise every day. She was very physically fit; she was on the basketball team in high school in St. Louis in the 1920s, when women didn't do that. And she taught me to play tennis, taught me to walk and run, and I ran for 30 years pretty religiously.

I've always believed as a value that the government has a vital - not overwhelming, but vital - role to play in furthering human welfare and good. I think we have an important supportive role to play, hopefully intelligent and sensible.

If the economy is still going forward, even at 40 miles an hour, 50 miles an hour, I think most people will stick with President Obama. I think people look at politics like they hire a plumber. I hire you to fix the bad pipe. If you fix it, I'll rehire you. If you don't fix it, I'm not going to rehire you.

What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
